Does the iPhone 5 headphones have a mic?

Yes it has

As long as you are talking about the original earbuds which came with the iPhone 5, then yes it does.

There's a small plastic piece that holds a mic, and allows you to adjust the volume. It also lets you skip tracks or go back and repeat them.

When you receive a call while wearing the earbuds, you simply press the small piece once in the center to answer the call. Then the mic is active and you can leave the iPhone in your pocket and just speak naturally. It actually picks up very well.
