The weather term for how "heavy" the air is is humidity. Humidity measures the amount of water vapor in the air, affecting how heavy or oppressive the atmosphere feels.
Regions of cold heavy air are called highs. As cool air moves under warm air, the warm air is pushed upward.
The air drag was so heavy that it pulled me with it
Air pressure is the metric used to measure how heavy the air is. It is typically measured in units like millibars or inches of mercury using a barometer.

Yes. air is heavier than helium.
Air molecules do escape into space it depends on how heavy or hoe light they are. However, lighter molecules of air have greater velocities while heavy molecules of air has less velocities were gravity pulls the air downwards.
The weather term for how heavy the air is is "barometric pressure." This refers to the weight of the atmosphere pressing down on a specific area at a given time, which can affect weather patterns and conditions.
