New school

okay we are moving in like 2 weeks
and my lil sis is going to middle school and
when she go to the new school she was just wondering
like who to sit with at lunch

Tell her to talk to girls ahead of time, like in classes before lunch. That way she'll have someone that she's talked to to sit with.

girls that have the same interests as her

Normally they will put you with people from your class to show you around if they dont just ask the teacher. It seemed to work for me. Hope it works!
