Ruby has the best group of friends:
Clancy just wears whatever he feels like and does whatever he feels like whilst also being pretty much as smart as Ruby even though nobody ever really notices him. He's also proven his undying loyalty multiple times and if that's not a good best friend I don't know what is.
Del is brilliant at sport because she works at it, unlike Ruby who seems to be effortlessly good at everything she does but instead of being jealous of Ruby, Del sees Ruby as a friend and an asset who is a quintessential part of whatever sports team she's part of.
Red would literally provide Ruby with any outfit she asked for if she didn't already get Spectrum issued stuff - imagine Ruby didn't get rerecruited in LimE, I can see her going solo like a sort of Sherlock Holmes 'consulting detective' esque narrative, asking Red to get outfits from Sadie.
Mouse is a mess and we love her for it. She's such a mood to break her violin, borrow Ruby's and then waste no time in breaking that one too before profusely apologising, and Ruby is completely unfazed because she already knew without a doubt that that violin was not going to come back to her in one piece before she even lent it.
Elliot is just kind of there to call Hitch a butler, have crazy theories and provide Ruby with her breakfast donut but all of Ruby's friends have to be credited with rescuing the tapes in TyLB so he's included in that too, even though it was Mouse's acting that really did it.
All things considered, I don't think Ruby's friends get enough credit for putting up with her and vice versa.
