There are more atoms in cold air than warm.
yes the cool denser air sink while the warm less dense rises
"Cool air rises and warm air falls" is false. Cool air is denser than warm air, and therefore warm air will rise above cold air.
Colder air sinks downwards, as it is denser than warm air. It is denser/heavier than warm air because the molecules are more crowded than warm air.
Yes, cold air does have a higher density than warm air. For example, if you turn on the fireplace, all of the warm air rises to the ceiling. On the floor, the air is cooler.

Warm air is less dense than cool air.
Warm air. It's denser and can therefore hold more than cool air.
because it is denser &/or the molecules are closer together
Cool air is denser than warm air, making it less likely to rise. It also cannot hold as much moisture as warm air.

No, as cold air is denser.

Yes. Cold air is denser than warm air and thus the troposphere is denser in the winter than in the summer.
Warm air is less dense than cooler air.
No it's just less dense. For the same volume of air, warm air is lighter.
