The energy that is used by you to compress the spring to close the box is stored in the spring until some one opens the box and releases the energy in the spring.
Hydrel energy
Electromagnetic Energy does not require matter to be transferred...that is why it can travel through the vacuum of space.
convection
There are different types of energy transfers; the details depend on what type of energy transfer you are thinking about.
Visible or optical electromagnetic waves.
The wave that transfers energy through empty space is called photons (what light is made of ) are the wave particle which mediates electromagnetic energy, which includes radio waves, electrostatic repulsion, and magnetism. Also, the theoretical wave particle the graviton is thought to mediate gravitational attraction, however has not yet been observed.

The force.
Super Ball. :)
You can convert kinetic energy to practically any other type of energy.
Laser light.

Kinetic or potential energy are always present during energy transfers.

i think you cant classify electro magnetic waves. all em waves have sam energy.
Potential Energy.
