We are studying about Pascal's Principle, and I do not quite understand the whole concept of hydraulic lifts. May someone explain how this force changes from 5lbs to 100 lbs?

& If you can, what is difference between the units, n/m^2 and Pa?

1 N/m^2 = 1 Pa. Same thing.
Force = (pressure x area), which is what gives you a mechanical advantage.
Do NOT confuse force and pressure.
Pressure is the force per unit area, while force is the product of pressure and area. So a set FORCE on a small area will produce a PRESSURE, and that pressure applied to a larger AREA produces a greater FORCE. So the large piston in your diagram applies greater FORCE than what you apply to the smaller piston.
