ONLY IN GASES, as pressure increases, so does soluability. Think soda: soda containers are pressurized in order to stuff as much CO2 as possible in the liquid. In solids and liquids, changes in pressure make very small changes to soluability.
solubility generally increases with a temperature increase
in my opinion, according to Henry's law - if pressure increase, solubility of gases will increase as well. I would say that the solubility of oxygen at 2 atm will be greater than at atm.
Oxygen stored as liquid is highly flammable.
You get a mixture of liquid hydrogen and liquid oxygen. If this is done at ordinary atmospheric pressures, the oxygen will probably freeze, since its melting point is above the boiling point of liquid hydrogen. (I'm not sure of the solubility of solid oxygen in liquid hydrogen.)
Oxygen solubility in water is strange and does not follow "normal" solubility rules along with many other gases. The solubility increases as temperature decreases.
The reason that it effects the solubulity of oxygen is that it is gaseous while NaCl is solid at room temperature. The oxygen molecules are effected by the increase in pressure in the way that there are more of them per unit volume of air if you increase air pressure. This is clearly not the case for the Na and Cl atoms which are ionically bonded to one another and are therefore solid. If you want to know more about the reason that pressure effects the solubility of oxygen in water, have a wee look at partial pressures.

yes it does

I'm not 100% sure that "solubility" is the right word to use here, but the amount of dissolved gas in a liquid will decrease as the partial pressure of the gas above the liquid decreases.Basically The solubility decreases.
Oxygen is a gas (in both forms: O2 and O3) at normal pressure and temperature.
