The contestants have these aplenty. Including those moments where teams gave up well earned gems to get other teammates back even at the expense of their own chances of winning. And then there was that time in The Secret Temple when the entire team jumped on a teammate who was terrified of heights - yet had completed a heights-related challenge anyway.
Another moment from The Secret Temple is Desot opting to get Lymel's jewel when she had to sit out of the challenge Chariots due to illness. It put him at a greater risk of being eliminated but he still did it anyway and was successful.
Desot and Lymel's friendship in general is this.
Raven showing up to defend the warriors after they're tricked and captured by the feral children in The Dragon's Eye is both this and kinda scary.
Kenat, a tiny little redhead who went on to win the sixth series and never stopped smiling the entire time.
Raven giving encouragement to warriors who have a tough time facing their fears in some challenges (e.g. Leap of Faith).
The warriors hugging each other/giving each other handshakes or high fives when one of them is eliminated after Way of the Warrior in series 8 to 10.
Though a few of the warriors have disabilities, this does not have the viewer's attention drawn to it via dialogue so one has to be looking closely to notice Lemec missing a few fingers or Wenra having one hand to notice a physical disability; Raven treats them with the same amount of respect given to "normal" warriors and doesn't judge them based on whatever disadvantages they might have. Rather, he gives them a chance to prove themselves the same as anyone else and several of them have made it pretty far in the tournaments, the aforementioned Wenra making it to sixth place overall in the fourth series as his not often mentioned Moment of Awesome. The new Raven in Series 11 and 12 has the same attitude, treating Hanmor the same as the other warriors despite the latter having a prosthetic leg.
Any time Raven calls the warriors "fledglings". It's a good reminder that despite how strict he is, he does care about them.
The interactions between Raven of Old and the current Raven from Series 11 onwards can be this at times. Especially when the former gives encouragement to the latter.
In Raven: The Island episode 11, Haryad admits that he lacks courage hence why he is pessimistic about the odds of the warriors succeeding on their quest. Princess Erina gives him a You Are Better Than You Think You Are speech telling him that he is showing great courage by admitting his innermost fears and assures him that they can succeed in ensuring the warriors know what to do if they work together. It inspires him to attempt to be more optimistic as a result.
Anytime either Raven Of Old or the current Raven says something along the lines of So Proud of You in response to the warriors doing well in a challenge.
