Anyone have any experience with taking down multiple girls in a tight group?

There's a group of three girls I go out with sometimes (in college). One literally worships my cock. She has tried to hook up multiple times, pays for everything for me, and texts me every day. I'm interested in her the least physically though, but she'd be a great plate. Her other friends eye fuck me all the time and flirt when we're all out, but I feel like they're holding back because their friend is so into me. I also slept with another girl they hang out with before finding out about all this.

Is there any way to plate/fwb the first girl and still fuck her friends? I've been reluctant to make a move and cut off my options, but I think I'm gonna have to move soon.
