No. An air mass is enormous, spanning hundreds if not thousands of miles across. A tornado is a small-scale but violent storm.
Yes. The warm air mass that often plays a role in tornado formation is called a maritime tropical air mass.

Most often a warm, moist air mass collides with a cool air mass, a cold air mass, or both. However, such a collision alone will only form thunderstorms. Other factors are needed for those storms to produce tornadoes.
Tornadoes are a product of severe thunderstorms usually found where a warm, moist air mass collides with either a cooler air mass or a dry air mass.
Tornadoes typically form in a warm air mass, as that is what provides the energy, though it is often near a boundary with a cooler or drier air mass. However, due tot he pressure drop the air in a tornado is cooler than its surroundings.
These are: Tropical Tornado: or a Cyclone.
A tornado usually requires a warm, moist air mass, most often when it collides with a cool and/or dry air mass.
Usually a thunderstorm, but depending on the temperature a tornado can also form.
Generally, it doesn't. Air generally moves up in a tornado. When the funnel of a tornado descends, the air is not moving down. The funnel itself is due to the pressure drop inside a tornado. This cools the air that is drawn into it, causing moisture in it to condense into a cloud. As the tornado forms and intensifies, the pressure and core temperature drop, allowing condensation to occur at a lower altitude. In some tornadoes, however, air does move down in the center of a tornado. This occurs when a tornado is spinning so rapidly that air spiraling in from the sides cannot reach the center. Instead, air is drawn downward through the center.
The tornado forms from the already existing updraft of a thunderstorm. The thunderstorm has (and actually develops from) an updraft that occurs as a result of an ai mass being warmer, moister, and thus less dense than either the surrounding air or an adjacent air mass.
