The further any Pump has to lift or push water to get it to the surface the less pressure it will be able to make as an end result. More horsepower and Impellers are required as the depth to water increases.

You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.
That depends on the water pressure and the surface area that the water is pushing against.
It generally takes 2 feet of water to lift/move/carry a vehicle. Be safe- Turn Around, Don't Drown!
Hydraulic pressure required to lift a one ton load will depend on factors such as the size of the hydraulic cylinder, the mechanical advantage of the system, and frictional losses. As a rough estimate, for a simple hydraulic system with a one square inch piston and a one ton load (2000 pounds), you would need a pressure of 2000 psi to lift the load.
because the water pressure takes up some of the weight as you lift it in the water
Max lift refers to the maximum vertical distance the pump can lift water from its source to the pump inlet. Max head refers to the maximum pressure the pump can generate to push water through the system. Both values are important in determining the pump's capabilities for specific applications.
The maximum suction lift for a solid column of water is approximately 33.9 feet (10.3 meters) at sea level. This is because the atmospheric pressure can support a column of water up to this height before the water vaporizes due to low pressure.
The maximum height to which water can be drunk through a straw is about 10 meters (33 feet), due to the limitations of atmospheric pressure. Beyond this height, the pressure differential required to lift the water against gravity would exceed the capacity of a person's lungs to create suction.
Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
