Would it be fine to have Ami know Kazaki before joining up with the squad? Like they knew each other in the regular army though in different units.

I'd imagine that she would have been part of his squad the entire time since she's not a greenhorn. So yes, it is assumed that they will know each other already, along with any other members that aren't brand new to the Moon Demon Company.
