ya it kinda looks like a variation of a Marshall island acro most commonly recognized by its smooth skin, and bright green polyps that glow under actinics, the GARF bonsai is just a purple variation.
Or a very close relative.
Nice score! At this point it is impossible to guess at the ID's, although with coloration, you can take various stabs. You need more growth patterns and branching until accurate guessing can occur.
The last one looks like a Marshall Island Acropora Valida, though as others have pointed out it would be impossible to say for sure with some bleach and a microscope.
