I have found a couple of this in my baby reef that i cannot find any info about.

The first one appears to be a baby turbo snail...??

The other is a weird almost cotton looking patch.. i have removed it a couple weeks ago. .but it has grown back..

Second one is a sponge. Pretty common live rock hitchiker and a good filter so I'd just let it do its thing. The other though is hard to tell exactly, the pics are a bit blurry, but maybe baby margaritas or stomatella snails would be my guess
