(assuming the Gang means JD, Betty, and Martha)
Betty absolutely loathes them, 0/10 they’re the worst people alive “Veronica why are you friends with them?” But she’ll help when in need, and with swaying from Martha and Veronica. The only students she hates more than the Heathers are Kurt and Ram
Martha has a very very rocky relationship with them (the whole candy store note and party incident), but if one of them were to reach out and actively try to make things right, she’d be willing to forgive them. (That redemption arc needs to happen first, though)
JD sees the other Heathers as “Could be decent people if they switched their crowd, but we’re not on a ‘getting slurpees together’ kind of friendship” and Chandler as “Oh yes I’m going to put my lizard in her bed to-NIGHT” if he sees her doing something fucked up. He also enjoys dangling Veronica in front of her like bait.
