First of all , low oil pressure . i had an issue that when the car front rises or on a hill the oil pressure decrease . then i have changed the oil pump then everything was fine for a month .and then again the same issue came back , when i shift to reverse or keep standing on a hill . what do you suggest

second thing is leakage
there is leak near the Right front wheel driping is it from the ac ?

 

The A/C climate control box is closer to the middle of the vehicle, not near a wheel, but if it's a clear water, not anti-freeze it probably is from the evaporator.
