Yes. Asteroids have some gravity, but it is very weak because of their low mass in comparison to an actual planet.
No. They do not have enough gravity to hold on to the gasses.
The asteroid belt, is a "collection" of asteroids circling the Sun in between the orbits of Mars and Jupiter. A collection cannot have an atmosphere. A single asteroid does not have enough mass to "hold" on to an atmosphere.
Living on an asteroid would be extremely challenging due to lack of atmosphere, gravity, and resources like water and oxygen. The conditions would be harsh and inhospitable for humans. Additionally, the low gravity could have negative effects on the human body over long periods of time.
the gravity stops them from floating away
Yes, it is.
The sun
No. They do not have enough gravity to hold on to the gasses.
false, meters are asteroids in the earth atmosphere

Not yet. And you'll probably never want to put houses ON asteroids; you'll build caverns IN the asteroids for places to live. Asteroids are pretty small; even the larger ones don't have enough gravity to hold things down. And without enough gravity to keep an atmosphere, you'd need to have some sort of dome or structure to hold the air in. Caverns and tunnels will be easier.
In the old days they did believe that they were distant suns because of the fact of how big it was.
The sun's gravity doesn't necessarily cause the asteroids to move, however it does cause the asteroids to move the way that they do move. For example, let's take away the sun. Any asteroids around the sun would continue to move at the same rate that is was moving prior to the sun being taken away. However, instead of following an elliptical orbit around the sun, the asteroid would move in a straight line instead. So the asteroids can still move without the sun. However, it is the sun that makes the asteroids orbit around the sun. The orbit's tendency to want to move away in a straight line counteracts the gravity created by the sun. The results of these two forces is what causes the asteroids elliptical orbit.
The sun gravity is stronger

Gravity.
because there is no gravity in space
the gravity stops them from floating away
