You could do with pulling some out, especially if you have some with seed heads. It's difficult to pick out the features and I think there might be other things in there.
It's not centipede, st augustine or bermuda. Not sure about the other grasses. Does it form runners or have a central root? I'm inclined to think it's a weed, something like dallis grass, or possibly a fescue, but it certainly doesn't look like good lawn material.
