Yay for group poses! Amongst your options I like perspective the best, I would especially love perspective poses that looks like you are all flying
Other than that, something I would love to see is group poses with a fantasy or fairytale theme! Like doing magical things, maybe performing an ancient ritual or portraying something mythological like nymphs and satyrs frolicking about or at leisure. Not necessarily in a romantically way, but touching, leaning on each other cuddling up together. Or fairies interacting in a group animately talking with each other or maybe just people sitting around a fire telling stories
And dancing, if possible lifting each other up while doing it, twirling around, dancing like fairies in a ring. Or some medieval type of dancing or courtship. Maybe also two people dancing while the other one is playing an instrument.
