What is this stuff on my live rock



I think this yellow stuff is a sponge? I seem to have a lot of it in the tank, most of it in dark places. This one in specific is growing on the frag of a dead coral, the white stuff is glue.



Here is another sponge looking thing, looks puffy. I'm also going to assume the green stuff is coraline algae.



Here is the one I'm having trouble with, I'm not sure what this is, the orange color almost looks like the color coming from rusting metal, but a bit brighter.

Something to note, it's not cyano or slime algae.

Looks like sponge, hair algae and cyano to me..

But I really can't see well as the pictures aren't focused that great and blue..

Tip.. turn off your blue light channel when taking ID pictures..
It will help with color rendition and should help focus some too..
