Yes. Their density is less compared to liquids and solids. But they definitely have mass since they are composed of the same molecules (or atoms) as the denser substances. The only difference is the inter-atomic or inter-molecular spacing, which is much higher than the liquids and solids.

Yes.
Look at this periodic table: http://www.dayah.com/periodic/

Yes. They can be compressed and fill smaller containers, but the mass equals weight and an empty gas cylinder is much lighter than a full cylinder.

Absolutely. Massive stars are formed from cold gas clouds many light years across collapsing in spots through gravity. Gravity always signifies mass.

Yes. Because they are also composed of atoms. And atoms ave masses. Unlike light, which is a wave and no mass.

yes...it is the third form of matter....the basic description of matter is 'anything that occupies space and has mass' so it goes to say that gases has mass...

Even atoms have mass! So yes, gas has mass.

Yes-
Matter is anything that has mass,
and gas is matter
Therefore gas has mass
