How many fish to add at once

Hello All:

I am thinking of buying a sailfin/algae Blenny and two or three purple eye anthias. Can I add them all at once?

Water is good. It is a 95 gallon corner bow front.
Temp: 79-81
Ammonia: 0
Nitrites: 0
Nitrates: 5-15 depending on the day
pH: 8-8.1
Sal: 1.0235-1.025 refractometer

"So far" their tank mates would be:
3 green/blue chromis
2 ocellaris clowns
1 red flame angel
1 cleaner shrimp

Can I do this at the same time? Thanks!
