No it's not.

It is a chemical property.
I suppose it would be a physical property.
No. This is because it is demonstrating the fact that it is less dense than the air. Density is a physical property. Therefore the helium balloon rising to the ceiling is not a chemical property, and instead a physical property.
It is a physical property.
This is a chemical property.
Air is a noun and not and adjective, hence it can not be a property. Gas would be a physical property describing air. Inert (for example) would be a chemical property.
Combustibility is a chemical property.

warmth and air
Blending air into ice cream to give it a lighter texture is a physical property. This process does not change the chemical composition of the ice cream; it simply alters its physical characteristics by incorporating air bubbles to create a smoother and softer texture.

I suppose it would be a physical property.
This is a chemical property. The reaction of green carbonate with moist air to form a different substance involves a change in the chemical composition of the substance, indicating a chemical reaction.
Chemical property
It is a physical property. Any gas that has a lower density than air will float above air. This is similar to how if you pour oil into water. The oil will float on the water because it is less dense.
