It might have a tenuous (ie very, very thin) atmosphere made of oxygen and ozone, but as far as I am aware even that has never been proven.
No, there aren't because the moon has no atmosphere.
It Is Made Up of A Thin Layer Of Oxygen That Is To Thin to Support Living Organisms.
So far: Venus, Earth, Mars, and Jupiter's moon Ganymede.
Ganymede experiences the same mild temperature change as Jupiter as it orbits the sun. However due it is negligible atmosphere of 0.1 Pa, and surface of water ice, it's is restricted as to what it can experience in the way of seasonal change.
No. Titan was originally though to be larger than Ganymede, but close inspection revealed that Titan is smaller than originally thought. Titan appears somewhat larger than it really is due to a dense haze in its atmosphere.

Ganymede has a extremely thin atmosphere mainly composed of oxygen however is extremely tenous so there it's almost no air
Ganymede has extremely thin atmosphere that consists of molecular hydrogen some trace amounts of water and Ozone, it also has an Ionosphere and magnetosphere

Ganymede has no atmosphere. It is the largest moon in our solar system, but we are not aware of any form of life that might find its surface hospitable.
