Move everything within Collider around an specific angle

I have a rubiks cube like constructionand now i want to move it like a rubiks cube. ive got a collider for every move that is possible within a rubiks cube, so speaking about a 5x5 rubix cube there are 15 colliders, but i have no clue how i can get every object within the collider and mover it around a specific angle for 90°.

im looking into the trigger section right now but it seems im looking for the wrong section or im just to stupid to get it, not sure right now.

can you give my some hints maybe?

would be grateful....

EDIT: Got some hints from a friend but im still a bit clueless.... and got some
