Chemical energy (originally form the Sun) in your muscles is used to impart potential energy to the object you have lifted.
Potential energy
When you lift an object, the energy transferred to the object is called gravitational potential energy.
kinetic energy
If we use a inclined plane to lift a object then the amount of energy used decreases applied force and wok

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.
Potential (gravitational) energy is transformed into kinetic energy. So, for instance, if you lift an object, you're storing energy which will act on the object once you let it go (increasing velocity).

By raising the object to a higher position. The potential energy also depends on the force of gravity, and on the object's mass, but for a given object (and for a given planet!), you have no control over these.
Yes. It is easier to push an object up a plane than lift it straight up. It does not reduce the total amount of energy needed to lift it up.
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.
