An electric fan does not, normally, store any form of energy. It is a machine which works in response to energy supplied - at the time - and stop working when that energy supply is stopped.
Electric energy (stored beforehand) --> Mechanical energy (used)(causing fan to spin; producing wind)
Electric energy to kitenic energy
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
=electric fan-electrical energy to mechanical energy!=
Because it is. Gravitational potential energy is energy stored in the gravitational field, electrical potential energy is energy stored in the electric field, magnetic potential energy is stored in the magnetic field, etc.

The fan itself stores no energy. If the fan has batteries these sore chemical energy.

An electric fan is not "an mechanical energy". An electric fan converts electrical energy into mechanical energy (the movement of the fan blades, and hence, the movement of the air).
Energy is not stored in lights (not electric ones at least). Energy is used by lights.
The electric fan converts electrical energy into mechanical energy used to turn the fan blades, so no.
electrical energy into mechanical energy.

chemical to mechanical energy
Yes that's what batteries do.
In a battery.
