I feel ya. You can either play nice and invite one of the girls over to hang out or go shopping or dinner with. Pick the girl that you feel is the easiest to talk to and most relaxed and less snobby out of all. If this goes well then it might help ease the tension a bit abs hopefully the girls will interact with you more. Try that if you really want a relationship with those snobby girls. Personally I wouldn't care too much because you are putting in the effort to have a relationship with the girls and it can't all be 100% from you, those girls also need to put in effort as well. Your bf needs to tell his friends to straighten up their snobby gf's. It's a respect matter and those girls don't respect you at the moment and the guys could care less. At this age I wouldn't put up with this type of middle school bs.
