potential energy it is directly proportional to height of object above ground
Double the first potential energy.
The higher above the ground an object is, the greater its potential energy.
Potential energy is stored energy. It has nothing to do with consuming or using energy - although you need to use some other energy to increase an object's potential energy. For example, in the case of gravitational potential energy, an object above ground level (or any other reference level chosen) has a positive potential energy, while an object below ground level has a negative potential energy.

potential energy it is directly proportional to height of object above ground
You are changing the object's gravitational potential energy. Gravitational potential energy is the energy due to position of the object above the Earth. This energy has the potential to be transformed into Kinetic Energy if the object falls.
Double the first potential energy.
When an object is lifted from the ground, it has potential energy because of it's position.
The higher above the ground an object is, the greater its potential energy.
3 times the original potential energy
After water or anything else falls to the ground it has no potential energy anymore. When mas is elevated it has potential energy. When it falls, the potential is converted to kinetic energy. That energy is then converted to light, heat, sound or compression of the object on to which the mass fell. But then the mass has no more potential energy.

Yes, a falling object has only potential energy at its highest point at rest. The same object will also have all kinetic energy and no potential energy the instant just before striking the ground at its highest velocity at ground level.
Any object that is at "level zero" has zero potential energy. In the case of gravitational potential energy, this level is sometimes defined to be ground level, sometimes (in Astronomy) at an infinite distance (in this case, any object that is closer than infinity has a negative potential energy).Any object that is at "level zero" has zero potential energy.
