CALLING ALL WRITERS?!?

You have too many characters to develop in depth in a novel. You should select one from whose point of view you wish to tell your story. The others then would become ancillary characters, her friends (uming that your protagonist becomes Lindsay). Since they all seem to be teenagers, high school age, you can have them either be friends, competitors, interacting as you like. Briefly, you would describe the secondary characters, and through their activities reveal their histories and characteristics, work those into the story as they are required. From your descriptions, I think that the obvious plot of your prospective novel would involve some sort of high school story. One or more of the boys would provide romantic entanglements for your main character, predictably. But, your major problem, as I see it, is to create an original and unique story for your characters; they are potentially intriguing as you've portrayed them; to interweave them into a cohesive and provocative plot will require your inventiveness and active imagination! Good luck!
