I agree with mr_alberta. Some of the fish you have on the list will not get along. Multiple tangs is risky, though many do it successfully. Blenny's and goby's can also be aggressive toward each other.

Puffers and lionfish will, as mentioned, may eat smaller fish, invertebrates, etc. Flame Hawkfish can also prey on invertebrates.

I'd pick 4-6 fish that you are fairly certain will co-habitate peacefully. But be sure not to dump them all in at once, either! Add one at a time (with the exception, perhaps, of a clownfish pair).

I'm generally not a fan of keeping most starfish in aquariums. With the exception of brittle/serpent starfish (and perhaps sandsifting starfish), they have a pretty dismal survival rate. In general. I know there are exceptions.
