Help Identifying SPS Species

[Coralreefin]

I thought I would finally start Categorizing the different SPS I have... Unfortunately most are tiny! Let the challenge begin:

Coral 1 - grenish base with pink ends

Coral 2 - all green:

Coral 3 - from wholesaler, potentially green base with purple tips

Coral 4 - blue base with yellow cirlces around polyps

Coral 5 - one on the left is green with blue tips, the one on the rights I think is a red planet

Coral 6 - last one, left is green turning white (how it grows not bleaching), middle is really cool blue green, right is neon green

Is there a better way to try and identify acropora? Thanks.
