The first picture is Coenocyathus bowersi which is a colonial cup coral. It is usually tan or pink, but can be almost white, and sometimes purple.

The most common place to find it is in overhangs, holes, and caves. If you put your head in and look up it is fairly common. It is also found in the open on the sides of rocks, but prefers shady spots.
