I want to know what it is, if it is harmful to my tank, and how to prevent it. The other two I'm told are coralline algae and just posted because I've never posted pics before and wanted practice. :)

All of it looks like coralline to me. :D
 
Oh, I guess there's two with the fuzz...oops...how did that happen? Oh well. I did forget to mention that it looks velvety in the tank but I haven't actually touched it (to my knowledge). As you can probably see, its by the shrimp. Oh, is the shrimp male or female? It said online that females will have blue ovaries but I don't know if those would be located where that shrimp is blue, you know? Its like in the armpits of his big claws. And what other inverts can I put with it?
 
Looks like red slime algea. They make a red slimr away, small bottle @ big box pet store i cheap.

Is that fuzz on all the rocks on just those ones? If it's only one a rock or two, then just pull that rock/rocks and let it completely dry out for a few days to weeks; from what I've read, that stuff can spread and cover all of your rock. It looks pretty gross when it takes over.

I think its only on two of them but I could only find the one to take a pic of. I'll have to closely examine them all and take out the ones with it on them. The red stuff is ok, though, right? Is it slime algae like cgodfrey1 says? Scott said it was coralline algae but by his own admission, he's no salt expert.

The red slime algae is an easy fix and can be treated in the aquarium, but I would remove the rocks with the fuzz (which is a different thing) in order to make sure it's all removed. The fuzz is not coralline algae and should be destroyed before it spreads.
 
Looks like Cyano to me (red slime algae). Commonly caused when there are flow issues. Are the areas where it's growing in a dead flow area of your tank? If so, toss a power head on it to help prevent future outbreaks.

^Correct. Treating for it is a temporary fix but if the root cause is not addressed it will come back. Removing the rock from the tank will kill it but also kill anything beneficial in that rock. When you put that rock back in you are adding dead organisms to the water. Increasing flow will help, less light per day will help, as well as checking nitrates and making sure your skimmer is functioning correctly. Is the skimmer big enough? Hope my suggestions help.
