An atheist is simply somebody who is not a theist. It doesn't mean that person believes a god doesn't exist, or believes a god is impossible.
The term "agnostic atheist" is a common one you'll see. Dawkins is an agnostic atheist.
In common usage, there are "agnostic theists" which means they believe in a god, but aren't 100% sure, and "agnostic atheists" which means they don't believe in a god, but think it's possible (e.g. not 100% sure a god does not exist). I don't completely agree with this usage, but it is what it is.
A "gnostic atheist" a "positive atheist" or "explicit atheist" is one who believes that a god does not exist. Just a plain old "atheist" is usually an agnostic atheist, but you'll never know until you ask.
Deists tend to be a grey area; Are they theists or atheists? Depending on the deist, they may have characteristics of each. They believe there is something like a creator being, BUT they don't worship it (typically) or think it requires worship or intervenes in this world.
Where a deist falls depends on whether you fixate more on the belief part of theism, or the requirement for worship of some kind, and what that implies.
The trouble with these terms is that they're all quite ill defined.

This doesn't have anything to do with agnosticism. I'm not sure where you heard that.

That's something else entirely. You might be thinking something along the lines of deism, or "cosmic paganism", new age ancient astronauts/star-gate style demigods.
