Well I am by no means a coral ID'ing expert, but in my opinion, they all look like Yuma's and Mushrooms.. I thought Ricordia had "same" size little bulbs, and Yuma took on smaller and larger "bulbs"... again, I am no coral ID expert
The orange one in my opinion looks like Yuma... but I have to admit it has a very similar characteristics to Ricordia.. I am simply going off of what I have kept and what I've seen.. so hopefully someone can give you correct ID's. I am interested to know myself.
Just my two cents...
