Since Mecury's inspiration is the god mercury/hermies I think super speed.

Cinders is glass Manipulation as a reference to Cinderella's glass slipper.

As for Ozpin I think its Soul Transfer, since he was able to transfer his soul into Oscar when he was killed by Cinder he probably did it last second before Cinder turned his body to ash using the fall maidens power like with pyrrah.
