Are these all different polyps?

Are these 3 different types of polyps? The ones on top, and the ones circled in pink were out when they were bought (I work at a kids science museum) but the part circled in red...are those sum polyps, or baby aiptasias? Just curious. Thanks

The ones you do not have circled are yellow polyps (Acrozoanthus sp. I think)
Pink circled ones are zoo's (Zoanthus sp.)
Red circled ones are also a type of polyp (not aptasia) usually called button polyps (probably Protopalythoa sp.)
