The most common method is to convert the heat into steam and use the steam to drive mechanical devices such as engines and turbines.
Sometimes it can, sometimes not. It depends, to a great extent, on the type of energy. Heat energy can only be converted partially into other types of energy; there are irreversible processes in the Universe, and converting other types of energy into heat energy is one of them.
First it is converted into heat. This is then usually converted to other types of energy through a steam engine.
Useful energy is energy that can be converted to any other type of energy. Wasted energy is no longer available to be converted - usually because it got spread out too much, or because it got converted to heat. Heat can be partially, but not completely, converted to other types of energy.
It isn't. Sooner or later some mechanical energy will be wasted and converted to heat. It is also possible to convert other types of energy into mechanical energy.It isn't.

Heat. In fact you can convert part of the heat into other types of energy, only if there is a heat difference between two objects - but you can never convert all heat into other types of energy.

More or less - however, any energy conversion is subject to the Second Law of Thermodynamics. A simplified explanation is that there are irreversible processes in nature, and that energy converted to heat can no longer be completely converted to other types of energy.
Thermal (heat) energy can only be converted partially into other types of energy. The remainder is "lost" for many practical purposes.
Heat energy.
Light can be absorbed, and converted to heat.However, if a light-bulb heats up, it's to a great extent due to other effects - for example in the old-fashioned incandescent light-bulb, the electrical energy gets converted FIRST to heat energy; a small part of that heat energy then gets converted into visible light. In other types of light bulbs, the light bulbs get hot mainly because NOT all of the energy gets converted into visible light; part of it gets converted into heat.
There are many different types of energy; the details of energy conversion are different, from case to case.
