How do i get closer to the friends i already have?

Im in middle school and my BFF just severed our friendship. i'm trying to get closer to my other friends but i'm having a hard time breaking through. I'm a part of a bunch of cliques. The Pretty-but-not-populars, the smart-weird-and-brainy girls, the cool-athletic girls, the not-so-cool-athletic girls, and the failing-rule-breaker-crazies. My old friend was part of the pretty-but-not-populars and now she's breaking into the pretty-and-almost-popular girls group, leaving me in her bratty dust. I really wanna get closer to the friends in the athletic groups and the non-popular pretties. Please help me with certain things to do, suggest, or say to get closer and maybe things to talk about too. Thanks a lot and don't ask about my old BFF or negatively comment on the cliques. Thanks! :) :)
