New Algae Id plz

I have noticed a couple of different types of algae and plant in my tank lately. I was wondering first what they are and if they are good or bad.
Thanks Cody

I have recently bought a bunch more zebra hermits and the have been doing a pretty good job cleaning up the hair algae. As the hair algea dissapears these new ones appear.
