Venus has an atmosphere much denser than Earths, while Mars has an extremely thin atmosphere. All the gas giant planets (Jupiter, Saturn, Uranus, Neptune) have significant atmospheres, as their name implies! Even Pluto, which is not officially a planet anymore, has an atmosphere.
Mars also has an atmosphere that is primarily carbon-dioxide, but on Mars, the atmosphere is extremely thin, and prone to high winds. The giant outer planets Jupiter, Saturn, Uranus, and Neptune have extremely thick atmospheres of hydrogen, helium, methane, and ammonia. Titan, the moon of Saturn also has a methane-ammonia atmosphere. For reference, Titan has roughly the mass as the planet Mercury (which doesn't have an atmosphere at all).
