Rate of energy conversion (any energy conversion) is called "power". The SI unit for power is the watt, which is equal to joules/second.
Energy can be converted from one form to another in a windup toy because when the spring unwinds, potential energy is converted to kinetic energy.
Yes, it can be converted into another kind of Energy. Example: The chemical energy of petroleum is converted to mechanical energy in a car engine with some loss as heat and sound energy. The mechanical energy is converted to kinetic energy.
mostly heat energy
Heat (thermal)
Energy converted into an undesirable form is wasted energy.

heat
Yes, any form of energy can be converted into any other form, although the conversion process is not 100% efficient and there will be some energy lost.
yes... for example electrical energy is converted to heat and light energy in a light bulb
Yes.
The electrical energy supplied to an electric motor
It is not converted, it's naturally changed from one form to another.
Heat.
