my guesses:
1) A. tenuis
2) A. yongei (green slimer)
3)?
4)? Maybe A. hyacinthus, tabletopping
5) Purple tip acropora...
6) ?
7) A. samoensis or A. humilis
Where did you get them? They look awesome, I'd be interested in getting some from where you got them!
Good luck with the acropora, they are tricky sometimes but can really reward you with their fast growth and dazzling beauty.
