yes
to have large diameter without increasing its weight.
By increasing the area of cross section in contact with the ground
Pressure in a glass can be reduced by either decreasing the amount of the gas in a finite space, or by increasing the volume of the finite space.
To increase the pressure you would have to reduce the diameter of the pipe. Half the diameter would give you twice as much pressure. Therefore to get 25 percent more pressure you would reduce the diameter by 25 percent giving you 37.5. Be careful though, this only increases the water pressure not the water flow rate.
The more gas you put in the specific object, the more pressure will build at the bottom of it and the gas will fill it completely.
It will increase? No it will decrease when the same amount of gas is held at constant temperature.
You reduce the diameter of the small piston. Or reduce the diameter and increase the travel of the small piston if you want the large piston to maintain it's previous range of travel.
You can remove the lid of its container. You can heat it, or you can reduce the pressure on it. Of course you could also increase the amount of gas at constant pressure.

That depends on the experimental conditions.In a situation of constant pressure, the density will also be constant.In a situation of constant volume, reducing the amount of gas will reduce both pressure and density.
compressor work on two principles 1)reduce volume of a constant amount of gas 2)adding more gas in a constant amount of volume positive displacement compressor works on first principle it reduces the volume of gas by applying force on it but gas amount is constant in every stroke or rotation thus increasing the pressure. centrifugal compressor work on second principle it adds more amount of gas in a given constant volume thus the pressure increase.
to maintain its properties and form to reduce the friction and deformation in increasing temperature and pressure.
