Increase the pressure of the gas inside
If you put a sealed jar full of air in the freezer, the gas pressure inside the jar will decrease. This occurs because the temperature of the gas drops, leading to a reduction in the kinetic energy of the air molecules, which results in fewer collisions with the jar's walls. According to Boyle's law, as the temperature decreases, the pressure also decreases, assuming the volume of the jar remains constant.
Helium is helium. Storing it is difficult as it diffuses through many substances.
Glass lids are slid under the gas jar when gases are being collecting. This is so the water vapor is collected.
As the water boils, it creates steam which increases the pressure inside the sealed jar. This increased pressure causes the air inside the balloon to expand, filling more of the jar.

Theoretically, they could expel gas into a sealed container like a jar and ship that.

Yes it's a gas, and if it is 'air' then it's a mixture of nitrogen, oxygen, argon and tiny amounts of other gasses.
I sealed the pickle jar after I took out a pickle.
A sealed jar with a large candle inside a small jar would not last 5 minutes. A large jar with a small candle most likely would last 5 minutes
This depends on the volume and pressure of gas.
Yes
How long can one keep a sealed jar of 'foie gras' in the fridge?
If the jar is still sealed, it is probably safe. But I'd be more concerned that the flavor and texture would still be good. I'd just get a new jar.
