As long as the static water level stays up you should be OK unless you start using more than 10 gpm. I would have suggested a higher gpm like 10-15 gpm and then whatever hp was need to pump from say 150'.

That 5 gpm is called thr recovery rate of the well, your capacity or storage is the usable water in the well and a 6" well has (IIRC) 1.5 gal/ft from the pump inlet to the top of the water.
