A sexy one (a Really Gets Around type or perhaps merely a glamour-obsessed pretty one)
An admirable but Wild Card kind of character (usually the narrator and wise Team Mom of the group who holds it together).
The wild card might be The Smart Gal or the Cool Big Sis but not the Team Mom. In that case, the mother figure will be be doubled up with either the sweet-naive girl, the sexy girl or even the mannish one.
This ensemble can typically be found in Schoolgirl Series.
May no longer be one after the addition of Nori and Nazuna.
Galaxy Angel has Milfeulle, the girly one; Forte, the Bifauxnen obsessed with firearms; Ranpha, the boy-crazy one; and Vanilla, the Emotionless Girl and silent observer.
Magical Pokaan's four girls. Yuuma is the sweet and naive mage, Liru the tomboyish werewolf, the vain vampiress Pachira, and the calm observer android Aiko.
School Rumble's primary cast locks up. Innocent and naive Tenma, tomboyish Mikoto, the Ojou Eri, and Akira, the silent, snarky observer.
Natsuiro Kiseki's main four childhood friends. The stubborn and tomboyish Natsumi, the realist and mature Saki, the hyperactive and childish Yuka, and the laid-back and quiet Rinko.
Lucky Star brings us two sets of four girls (they were even grouped as such in their Image Song releases).
In the manga, the second group is in fact a three-group. Patricia does not become affiliated with Yutaka in any way until volume 7, and is just a minor recurring character, appearing only in Omake until that point.
Since only about two members of its cast are male, Doujin Work also has an example. Innocent Sora, quiet Tsuyuri, tomboyish Najimi and the Office Lady Kaneru.
Quirky Miniboss Squad / Evil Counterpart team Schreient in the original Weiss Kreuz anime series, with Nanami/Tot as the sweet naive one, Asuka/Neu as the tough one, Karen/Schoen (German for beautiful) as the vain pretty one, and Chizuru/Hel as the sensible leader.
It's notable that the four male protagonists of Weiss Kreuz fit the trope rather neatly as well, with Omi as the sweet naive one (at least compared to the others; given that all four are assassins, none of them can be very naive), Ken as the masculine tough guy, Yoji as the Handsome Lech, and Aya as - albeit not always the wise one - the one who tends to exert the most authority in times of uncertainty or disagreement. The roles become even more apparent in Weiss Kreuz: Gluhen with Sena replacing Omi as the sweet, naive one and Aya growing more fully into the role of the wisest and most emotionally balanced one.
The Amazoness Quartet in Sailor Moon. PallaPalla is the naive childlike one and JunJun the tomboy (she even uses informal male speech patterns). VesVes gives the image of the sexy one with her whip but actually splits the mannish role with JunJun, and while CereCere is sexy and glamorous, she tries to be the most mature of the four.
This is because the Quartet are counterparts of the Inner Senshi (excluding Sailor Moon herself), who also form a Four Girl Ensemble. So do the Ayakashi Sisters, their counterparts in the second season.
Ami/Mercury is The Smart One and The Quiet One, Rei/Mars is the Ojou and the Deadpan Snarker, Makoto/Jupiter is The Tomboy (in the anime) and the Team Mom (in the manga), and Minako/Venus combines The Sexy One and The Ditz.
The Knight Sabers in Bubblegum Crisis — Nene is the cute naive one; Linna is a dancer with a different boyfriend every episode; Priss has the bad attitude and the tomboyish ways; and Sylia is the boss who keeps them all working together as a team.
Played differently in Tokyo 2040 — Nene was still the cute one, Linna switched to The Quiet One, Priss was the mannish/straightforward one, and Sylia was the worldly one with severe issues under her smile.
The original Macross has Captain Gloval's Bridge Bunnies: Claudia is the motherly/sisterly one, Sammy is the Moeblob, Kim is quite straightforwad and the Meganekko Vanessa is kinda the quiet one.
Also, Orihime's school friends aside of Tatsuki: Michiru (The Quiet One), Mahana (the tomboy), Chizuru (the Genki Girl, with huge traces of Lovable Sex Maniac) and Kunieda (the mature one).
Puella Magi Madoka Magica's four main Puella Magi: Madoka (sweet, idealistic, naive), Sayaka (The most romance-oriented of the group), Kyoko (cynical, ambitious) and Homura (calm, experienced). Mami initially played the role of the wise, experienced one as well, before dying.
Yama No Susume has this with Hinata (pushy, go-getter) and Aoi (ditzy and naive, the girly-girl to Hinata's tomboy), Kokona (pretty, feminine) and Kaeda (kind, experienced).
Comic Books
In Jet Dream, Jet is the leader. Petite is the sexy (stereotypically French) one. Marlene is the big girl who can out-wrestle most men, and Ting-a-Ling is the sweet, naive one.
The Discworld fic, The Graduation Class covers four mature entrants through their training to become full Assassins. The four women candidates fill these four niches: Johaana Smith-Rhodes is the pretty ditz, Alice Band the mannish rather butch one, Emmanuelle Lapoignard les Deux-Epees is the one who's been around the block a few times (Alice snarkily sums the three up as the virgin, the dyke and the nymphomaniac. What a trio we make.) They are bonded together by the older Team Mum type, Joan Sanderson-Reeves.
Film
The four girl coven in The Craft: Sarah, the wise one; Nancy, the Deadpan SnarkerGoth who doesn't care what other people think of her; Bonnie, who becomes increasingly image-obsessed and vain; and Rochelle, the sweet, quiet one (and Token Minority) who just wants the Alpha Bitch to stop her racist taunts.

The four girls from the Bratz movie, Jade (smart), Sasha (sexy), Cloe (sporty), and Yasmine (preppy). The Alpha Bitch immediately breaks them up due to her obsession with keeping cliques separate for some reason.
The starring D.E.B.S. squad is pretty much a textbook case with promiscuous Dominique, naive Janet, obsessive Max and self searching Amy.
Literature
Little Women is the Trope Codifier: Meg, the oldest, is the lecturer and mature example-setter who wants a husband and family; Jo is the tomboy who wants a career, fame, and fortune; Beth is the shy, gentle and musical one who wants to stay with her family; Amy is the vain and spoiled but later artistic and flirty young lady who wants to marry someone with money.

The Sisterhood of the Traveling Pants has Lena, who is a shy, introspective aspiring artist, Bridget, who is daring and courageous with gorgeous blond hair, Carmen, who is the organized one and the "glue" keeping the Sisterhood together, and Tibby, who is known as the rebel and disdainful one.
Marylin Kaye's Sisters series: Activist Lydia is the Team Mom figure, Cassie is the fashionista, Daphne is the shy and sweet one, Phoebe is the tomboy.

The American Girl books have the Montoya sisters: Ana, the oldest and the Team Mom (almost literally, since their mother is dead and she's already married with two kids); Francisca, the beautiful, fashionable, rebellious one; Clara, the diligent, prudent, preachy one; and Josefina, the youngest and the main character, who's chirpy and cheerful and tries to keep the peace between Francesca and Clara when Ana's not around.
Cathy Hopkins 'Mates, Dates' series has this with wise Izzy, sweet Lucy, bookish tomboy TJ and flirty Nesta.
J. Courtney Sullivan's novel Commencement, about a group of Smith students who become friends after sharing a floor their freshmen year, has: Celia, who probably fulfills the role of the "sexy one" as she is a Hard Drinking Party Girl who Really Gets Around, even though she's not the prettiest of the group; Bree, who is the "sweet naive one" - she starts out as an engagedSouthern Belle; Sally, a Neat Freak who serves as the Team Mom; and April, who fits the role of the "tomboy" as a Straw Feminist, Granola Girl and Deadpan Snarker.
Pretty Little Liars: Emily is the sweet and sporty one, Hanna is glamorous and popular, Aria's the artistic hipster Deadpan Snarker, and Spencer sort of replaces 'wise' with 'perfectionist.'
They each represent Aspects of Ali's personality.
In The Gallagher Girls series, there's Cammie, Liz, Bex, and Macey. The latter three fill out the roles for Beauty, Brains, and Brawn (Macey is the beauty, Liz is the brains, and Bex is the brawn), while Cammie is more of a Girl Next Door.

Live Action Television
Golden Girls: Rose is the ditz, Blanche is the slut, Dorothy is the snarker, & Sophia (Dorothy's mother) the Team Mom.
Despite age, Sophia is kind of more the snarker and Dorothy is more the level headed "mother" type.
Designing Women: Charlene, Suzanne, Mary Jo, & Julia (owns the business they all work for)
Living Single: Synclaire, Regine, Max, & Khadijah (owns the apartment).
Sex and the City: Charlotte (Idealistic, slightly naive, The "Park Avenue Pollyanna"), Samantha (slutty, cynical), Miranda (Deadpan-snarky, career-focused, less glamourous than her friends), & Carrie (romantic and the narrator who sees everyone's foibles)
Desperate Housewives: Susan (ditz), Lynette (snarker), Gabrielle (sexy), and Bree (Team Mom)
Women's Murder Club
Privileged: Megan (fulfilling the Team Mom role for both the twins and her own sister), Lily (the sexy one, more towards the Really Gets Around end of the scale), Rose (the well-meaning but not too bright Ditz) and Sage (the cynic and Deadpan Snarker)
Gossip Girl has Serena (the sexy, freespirited one), Blair (acts as overseer if only to reenforce her image as Queen Bee), Vanessa (the bitter cynic) and Jenny (while not The Ditz in the strictest sense, she is incredibly naive and easily led at times)
Short-lived (due to being lost inthe merger)WB series Related: eldest sister Ginny is the wise one, second-born Ann is the career-focused (least feminine) one, third sister Margie is the flirty one, and Rose is the youngest and most naive.
British series Mistresses has this:
Trudi: A blend of Team Mom and the "sweet and naive" type. A 9/11 widow with two children; has a tendency to get caught in awkward situations. The most motherly.
In the second generation: Effy and Katie split the "sexy" one; Pandora is the sweet, naive one; Naomi is the Deadpan Snarker; and Emily is the wise, nurturing one.
The girls of the third generation too: Mini is the sexy one due to her obsession with being pretty; Grace is the sweet and naive one who believes in stories and fairytales; Liv is the closest to the Deadpan Snarker; and Franky is the wise one.
Alternately, Mini is the pretty, naive one; Liv is the "sexy one" since she Really Gets Around; Grace is the nurturing Team Mom; and Franky is the mannish one.
In the American version, Michelle is the pretty one, Cadie is The Ditz, Tea is the snarky one, and Daisy is the Team Mom.
In season seven of Smallville with the arrival of Kara, we have naive (not so much "behind the scenes") Lana, mannish Lois, sexy Kara and wise Chloe.
The girls of S Club 7 were portrayed this way on their tv show. Hannah was The Ditz, Jo was the mannish one, Rachel was the glamorous one obsessed with her looks, and Tina was the wise one.
Although not all four Charmed Ones were on the show at he same time (since Prue died before Paige was introduced), the sisters still fit this trope. Paige was The Ditz, Piper was the Deadpan Snarker, Phoebe was the sexy one, and Prue was the wise Cool Big Sis.
Before Paige, Phoebe played a combination of the sexy one and The Ditz. Once Prue passed away, Piper took on her role as the wise Cool Big Sis but still had her Deadpan Snarker traits in tact.
90210: Annie is the sweet naive girl, Silver is the Deadpan Snarker, Adrianna is the one obsessed with glamour and fame, and Naomi serves as the mother figure for the group.
In the original series, Donna was the sweet naive one, Brenda was the Deadpan Snarker, Kelly was the pretty one, and Andrea was the smart one.
Pan Am: Laura is the sweet, naive one, Maggie is self-righteous and free-spirited, Colette is sexy and romantic and Kate is the independent, Team Mom type (and Cool Big Sis to Laura).
Victorious: Tori is the main character, the jack-of-all-trades in terms of talent and the most "normal" of the group. Tori's sister Trina is obsessed with fashion and quite ditzy and girly, Cat is childlike and naive, and Jade is the snarky bad girl of the group.
The girls on, well, Girls. Marnie is the level-headed, smart one, Jessa is the sexy free spirit, Shoshanna is the naive ditz, and Hannah is the lazy snarker.
The four students on Bunheads. The show hasn't been on long enough to tell but so far Boo is the sweet one, Sasha is the glamorous Ice Queen, Melanie has elements of being The Ditz, and Ginny is the smart one.
Nina Simone's Four Women more or less describe a more mature and tragic Four Girl Ensemble. First there is Aunt Sarah who is resilient and, perhaps, motherly, then there is Saffronia who may or may not be the naive girl (all we know is that she's bi racial), next there's "Sweet Thing" whose "hips invite you" and to conclude there is Peaches whose "manner is tough".
Kpop group Sistar fit this description. Bora is the sexy one, Soyou is the ditz, Dasom is the Deadpan Snarker and leader Hyorin is the big sister.
Newspaper Comics
My Cage: Norm admits everything how knows about women is what he's seen on TV, as depicted in this strip.
Video Games
The nurses in the sega brain trainer Brain Assist seem to have this dynamic.
Final Fantasy X-2 has Yuna (shy and sweet), Rikku (sexy/cute), and Paine (the tough girl), with former party member Lulu (out of the action due to her pregnancy) serving as the voice of wisdom.
A slight stretch, but Valkyria Chronicles fits as well, with Isara as the sweet one, Alicia as the sexy one (she's the romantic interest in the story), Rosie as the tomboy, (though an argument can be made for the reverse), and Ellet as the wise one (she's recording the exploits of Squad Seven).
A sidequest in Tales Of Symphonia involves a mother asking the party to find her four daughters within the city. The daughters are an obvious Shout Out to the girls either from Little Women or perhaps Bakuretsu Tenshi - right down to their names and personalities (Jo will be impressed that you could tell she was a girl, regardless of if you really could).
The female party members arguably fit this trope as well; Raine is the wise motherly one, Colette is the sweet one, Sheena is the sexy one and Presea (despite having hints of Token Mini Moe) is the tough one.
Knights of the Old Republic 2 (assuming you mod it to get the Handmaiden with a female player) has Visas (naiive), Mira (cynical/sexy), the Handmaiden (mannish), and the player (leader).
Kreia could also fill the 'leader' mold, but in an extremely dark, twisted way as she manipulates the entire party to stick together.
Normally, the three female party members in Dragon Age: Origins comprise The Hecate Sisters ensemble, but with the DLC-only character Shale they become this: Leliana (sweet, naive), Shale (mannish snarker), Morrigan (sexy, cynical), and Wynne (wise, motherly).
Dragon Age II, assuming female Hawke: Merrill is the naive one, Aveline is mannish in the extreme, Isabela is over-the-top in her sexuality, and Hawke is the Only Sane Woman.
Still applicable with only female party members: Bethany as the sweet, naive one (at least in Act 1), Aveline as the masculine one, Isabela as the sexual one, and Merrill as the wild card (on account of her blood magic and/or her Cloud Cuckoolander nature).
Female members of your squad in Mass Effect 2 include Tali (Not really naive, but quite sweet), Jack (very mannish), Miranda (sexy, cynical), and Samara (wise, motherly). The addition of Liara as a Guest Star Party Member and Kasumi in DLC mods throws off the dynamic a bit.
Samara doesn't exactly fit the motherly part of that however, her Establishing Character Moment is coldly killing an opponent who was already down, and she threatens to murder the Player Character (among other people) several times over the course of the game. She's seen quite a bit, being an asari, so she's plenty wise. Just not very motherly.
In the online game Disney City Girl, you as the main character are a member of one of these, with the other three girls being your college friends who drop by frequently. Veronica aka V is the sexy one, Jenna is the Genki Girl, Olivia is the motherly and mature one, and since you're a Country Mouse you play the role of the naive one.
KOF 99: King (mature), Blue Mary Ryan (sexy), Kasumi Todoh (Genki Girl, sorta) and Li Xiangfei (naive)

KOF 2001: King (back to mature), Mai Shiranui (sexy), Li Xiangfei (Genki Girl) and Hinako Shijou (naive)
Web Animation
Homestar Runner'sTeen Girl Squad has Cheerleader as the slutty one, So And So as the nerdy naive one, What's Her Face as the wise one (relatively speaking), and The Ugly One as the tomboy.
What's Her Face is more of a tomboy than The Ugly One, but then... The Ugly One doesn't really fit any of the categories anyway.
Liv world features a Brainy Blonde, a clumsy tomboy, a fashion-savy black girl, and a drama queen (is she hispanic, or asian?).
Sky Dancers brought us Camille (the creative black girl), Jade (the asian ballerina), Angelica (the tomboy teenie-bopper) and Skyla (the wise platenum-blonde leader of the team).
Recess gives us the Ashleys. Blonde leader Ashley A., African-American and snarky Ashley B., athletic Fiery Redhead Ashley Q., and Hispanic and quiet Ashley T.
My Little Pony: Friendship Is Magic has Pinkie Pie and Fluttershy both in the role of the sweet, naive one, Applejack and Rainbow Dash both in the role of the tomboy, Rarity in the role of the glamour girl, and Twilight Sparkle in the role of the smart one/big sister.
Winx Club gives us Musa, Stella, Flora and Tecna working without Bloom temporarily in season 1, giving us a temporary four-girl ensemble. Stella qualifies as the sexy one and The Ditz, Flora is the Team Mom, Musa is the tomboyish one and Tecna is the smart one.
COPS has this with the four girls in the series. Nightshade is the sexy one, Mirage is the motherly one, Ms. Demeanor is the brawny one and Mainframe is the smart one!
The Powerpuff Girls have this in episodes where Princess Morbucks appears. Blossom is the smart one, Bubbles the sweetie, Buttercup the tomboy, and Princess the Alpha Bitch.
