The air inside a jumbo jet is generated from the engines and is fed into the cabin and recirculated every 12 minutes. The air is calculated at approx.1 ton inside the passenger cabin. When on the ground and parked, the aircraft skin can easily be damaged by the slightest knock, but when fully pressurised the skin becomes rock hard.
You've seen in the movies, people being sucked out of the plane at great speed. this is caused by 'explosive decompression'. So always stay belted in your seat.

The air in a Jumbo Jet when flying at high altitude is brought to a pressure slightly lower than normal atmospheric pressure and extra oxygen is added to maintain near normal oxygen content.
The density of the air will therefore be a little lower than normal too i.e. a little lighter than on the ground.

Air pressure in the aircraft is equivalent to the outside air pressure at an altitude of about 8000 ft, so the aircraft will actually contain less air than when on the ground.

pVg where p is the density of air, V is the volume of air and g is the acceleration due to gravity. If you meant pressure I think it is atmospheric

Slightly heavier than usual, because it compressed.

I don`t know, but, REME, might have idea, compression.
