I am looking to pump water from my well at bottom of hill, roughly 60 feet uphill, for a run of approximately 600 feet. Will a 1 inch pex run be sufficient to use for this type of application? Im getting about 90 PSI from the well at about 1o gpm. I will be putting a pressure pump and water conditioner at the top of the hill as well in the pump house.

Prescriptive codes don't address the connection at less common angles, so base the connection off more typical ones using bolts, structural screws, blocking, and steel tension ties.

60 ft of head is around 26psi.
1 in pex at 10 GPM has a pressure drop of 5.5 PSI per 100 ft. or another 33 PSI
So planning on loosing 60 PSI on the trip, you should see 30 PSI at the top of the hill.
An accumulating tank (perhaps two) and pressure pump will help if you want higher pressure.
Starting with 90 PSI at the well, it does not sound like you would need an additional pump at the pump house. If you install one, make sure the pressure is well within the PEX ratings at the temperatures you expect.
PEX should work ok. Make sure to install below the frost line, and use sand to protect the pipe with sand or similar. I would put a couple wiggles in the line on the way and make sure service loops are provided to allow for expansion and contraction with temperature. Depending on your soil conditions, you may want to consider running inside a PVC sleeve, or using a layer of sand or other fine fill around the pipe.

But what do I know. Probably want to consult with a local plumber and/or your building codes department.
A 1-inch PEX run should be sufficient for pumping water uphill from your well, given your 90 PSI pressure and 10 GPM flow rate. Make sure to properly size your pump and consider any friction losses over the 600-foot distance.
