3 ID's: a purple branching, a blue tipped branching, and a purple sps

These were gifted to me by a few reefers a few days ago and I am sure the colors are not optimized.

1) This one has light blue tips and a body that is brown, but I wonder if it is heading to green:

2) This one is deep purple without any highlights and grew in the other tank straight up, like a cluster of stalagmites:

3) This one was a pretty large stag/branching type coral in his tank (undergoing a bit of STN). Currently it is a washed out purple color:

The first i would guess Acropora loisetteae http://coral.aims.gov.au/speciesPages/species_metadata/0837/view#

The other two are too small and the pic is blurry. So I can assume they are Acros but that is all.
