The rainwater will absorb small amounts of oxygen as it is falling, so reducing the concentration. However, as the deposited rainwater evaporates, the situation reverses, and the concentration eventually returns to that previous to the rainfall. Other factors to consider, are that rain falling onto earth will, along with the oxygen, be absorbed and used as a nutrient by plant and animal life, to be returned to the atmosphere by photosynthesis and the decay of animal carcasses.
The amount of oxygen absorbed by the rain will be dependant on many factors, including droplet size, solutes, temperature, pressure etc.

The amount of pure oxygen would be less, the O2, but there would be more O in H2O. When it rains the moisture in the air increases and displaces the gases that make up air, namely N2 and O2. So the free oxygen is a bit less, but the total may depend on the O in H2O. That's why moist air is less dense than dry air because H20 weighs a lot less than the N2 or O2 it has displaced..

Although oxygen gas, (other than in the molecule H2O), is dissolved in water - it comes from the plant life in the water.
Oxygen does not dissolve in the rain.

Don't think so. Water has oxygen.
Air gets cleaner and so oxygen will not deplete.
Heat decreases oxygen.

Not sure if there's more oxygen I haven'y heard that, but there is often the smell of a gas called petrichor.

probably not cause all the trees haven't been cut yet. oxygen keeps on coming.
