Hey man, I feel ya. Shit can be rough in your situation.
Your mindset is wrong. Don't try to 'act cool' or impress the other kids. During lunch, just find some guys/girls and ask to sit with them.
A comfortable way is to meet a girl/guy in class, even just a very superficial thing, and find that person during lunch. Ask them "hey [name], mind if I sit with you?" If you're a normal guy, they will be okay with you chilling.
The idea is to not try to impress people, just be a chill normal guy. Make an effort to hang around the people you want more. When the weekend comes around, ask some of them "you know of any parties going on?" or something like that.
Don't be afraid to be new.
Make sense?
edit: DO NOT COLD APPROACH IN HIGH SCHOOL. It's as simple as making an effort to hang around these people and putting yourself in situations where the girls are. (like lunch time and parties or grabbing food after school). Make your moves at the parties or after some time -- you don't need to rush things when you're going to see the same people day in and day out.
