It helps to think of "work" as the transfer of certain types of energy.
No, work done by friction is always negative because it opposes the direction of motion. Friction always acts in the opposite direction to the force causing the object to move, resulting in a loss of energy and a decrease in the total mechanical energy of the system.
Work done is the measure of energy transfer that occurs when a force causes an object to move a certain distance in the direction of the force. It is calculated as the product of the force applied and the distance moved in the direction of the force. Work done can lead to a change in the energy of an object.
Energy is equal to the ability to do work. Energy can exist in various forms such as kinetic energy, potential energy, thermal energy, and chemical energy.
No, kinetic energy and potential energy are not equal in a system. Kinetic energy is the energy of motion, while potential energy is the energy stored in an object due to its position or state.
Total minus kinetic energy is equal to potential energy. Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy of motion.
The work is done when the fan moves air, imparting kinetic energy to the air.

Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time

it depends upon the systems displacement and your workdone

When a force (no matter how large it may be) is applied to any object without a distance being moved,it cannot be workdone because,workdone = force x distance.
