Almost all of them; you just can't breathe it without dying.

None that have the same composition of air as earth. However, we're still searching. So, far in our solar system, we've found some planets with air that have a co2 gas as the main element of air rather than nitrogen as it is on eartlh.

Air consists of about 78% nitrogen, 21% oxygen, 0.9% argon, with the remainder numerous trace gases. No other planet in our solar system has air. Whether there's some planet with it, way out there, orbiting another star, nobody knows.

Venus, Mars, Jupiter, Saturn, Uranus and Neptune all have air. But none of these planets has enough oxygen in its air for us to be able to breathe it. Also, Mars has air so thin the even if it was pure oxygen we still couldn't breathe it.

Well Venus has an atmosphere but one that is very hostile to any form of life that we can envisage, Mars has a thin one and you could well argue that the gas giants also have very deep atmospheres but none that we know of, and certainly none in our solar system, have an atmosphere containing the gases in ours to the proportions that we have (or even close!!)
