I think new they have 6/32, so figure they're about half gone. YOu need to replace them at 2/32".
Depending on the hole, you could get it patched from the inside (cheapest) to stop the leak, or replaced. I'd replace both rears as a pair and both fronts as a pair to help it not hurt the wallet as much, and replace a single tire unless there's less than a 1/32" of difference between the replaced tire and the new tire (meaning it's practically brand new). The exception to this is if you're changing brands and/or models...then I'd do all 4.
That's my opinion on it.
