Three SPS - any idea how they are called?

Posting some shots of my acros:

This sps is green with red/brown polyps. The piece shown grew back from a piece left when I cut back the whole colony. It appears to be one of the hardiest in my tank.

I think this is a millie and it is red with green polyps.

Another frag that never really grew a lot. I hope it finally comes around since the tips are coloring up in blue.

Any idea what these corals might be called?

I think the first one is a Spongodes.

First one is not spongodes.. look like an acro. Too small too tell

2nd is millepora (possibly prostrata).
3rd is too small, but possibly Lokani.
