To calculate head pressure in psi from a head height given in feet you multiply by 0.434.
15 x 0.434 = 6.51 psi
A vacuum pump relies on creating a pressure difference to lift water, and atmospheric pressure can only support a column of water up to approximately 10.3 meters (33.9 feet). Beyond this depth, the pressure exerted by the water column exceeds the atmospheric pressure, making it impossible for the vacuum pump to lift the water. Consequently, for wells deeper than 10.3 meters, alternative methods, such as submersible pumps, are required to extract water effectively.
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.
I must assume you mean uniterrupted column of water! The maximum suction lift of a column of water is the height of a column of water (inside a vertical pipe for instance) that can be supported by atmospheric pressure i.e. approx 14.69psi or 760mm Mercury. You should be aware that suction does not cause water to lift. Suction produced by various kinds of pump merely removes air from above the column of water and this allows atmospheric pressure to act upon the base of the water column. The water column is therefore pushed upwards by atmospheric pressure from below rather than pulled up by suction from above. The density, vapour pressure and surface tension of water vary slightly with temperature and atmospheric pressure also varies slightly with weather conditions. Thus the measured height of the water column may vary slightly according to the conditions prevailing when making the measurement. A good approximation at room temperature is 33 feet or 10 metres.

The max height for mercury to be raised in normal atmospheric pressure is 76 cm. As the relative density of mercury is 13.6 then the max height in case of water is 13.6 times 76 cm. This would be equal to 1033.6 cm. Some 10.336 m.
