I am cleaning my tank and these are under the rocks and in the sand what are they? Will they hurt anything? Should I get rid of them and if so how?

bristle worms, they only hurt if you touch them and no they are scavengers and will not hunt anything down and harm it. part of your clean up crew

What Chris said. Bristleworms, a vital part of your cleanup crew. They are good guys, dump 'em back in the tank.
