What gauge ground wire should be used for a 220 V 3 HP motor in a well 400 ft deep?
No responsible person will answer this question without observing the situation first-hand. If you don't know how to calculate the answer yourself or look up the table in your local code books, then you shouldn't be installing a motor that size. 220V, 3HP motors are going to be multi-phasic, and that's going to require special connections.
Consult a local electrician.

How deep should a temporary electric service pole be set in the ground?
There is no specific depth stated. Two to three feed deep with staked angular support from the pole to the ground will do the job fine.
What are the advantages disadvantages of 2 or 3 wire deep well pumps?
2 wire pumps have the start controls inside the motor, 3 wire have a separate start panel that needs to be mounted in a dry location above ground. If there is a problem with capacitors or relays, the 3 wire panel can be repaired easily. Not so much with the 2 wire. 2 wire can be cheaper and quicker to install.
Can a small 12 volt 200 watt electric motor run safely off a deep cycle battery whilst the battery is being charged at say at 20 amperes?
Should be OK. If the motor draw is 200 watts, and the charge current is 20 amps, you've got (12 x 20) = 240 watts in and only 200 out. The battery will charge at a rate of (40/12) about 3.3 amps, so be aware that (i) the battery will take longer to charge than if the motor wasn't running, and (ii) once you stop the motor, the charge current is the whole 20 amps and you'd need to be sure that the battery won't overcharge.

Why does your grounding meter read OL from gen to 1st ground rod and from 1st to 2nd ground rod get 28.51 ohms?
Code requires that the resistance between the two grounding electrodes be 25 ohms or less. You don't mention how deep they are or how far apart they are. THat will make a difference. Or it could be the soil they are in.You need to get the resistance down
