They do need a medium
Never. Sound propagates as longitudinal waves which are a kind of mechanical waves. These waves require a medium for them to pass. The medium can be either solid, liquid or gaseous. Thus, in empty space i.e. vacuum, sound can never pass.
Energy is not transferred in the opposite direction of wave propagation because waves transport energy through oscillations or disturbances in a medium. These disturbances can only move in the direction of the wave itself, not against it. In a wave, energy is transferred from one point to another by the movement of the wave particles in the same direction as the wave itself.
No, individual particles of a medium do not move along with a wave. Instead, they oscillate back and forth in a motion perpendicular to the direction of wave propagation. This motion of particles helps to transfer the energy of the wave through the medium.
When energy transformations occur, energy is never created or destroyed. Instead, it simply changes from one form to another, such as from potential energy to kinetic energy or from electrical energy to thermal energy. This principle is known as the law of conservation of energy.
Magnets never run out of energy.

Passive transport never requires energy - hence the name passive. Active transport requires the input of energy. Two types of active transport are; primary (using pumps) and secondary (using anti or symports).

Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.
Walk. Alternatively, I'd invent transport myself!
ATP is not produced by passive transport processes like diffusion or osmosis. It is also not directly produced by light energy, but rather by the process of photosynthesis in plants using light energy. Additionally, ATP is not produced by the electron transport chain in anaerobic respiration.

Not if it is not safely secured.
