Interference means two waves meet each other. If the waves are in same phase, they'll enhance each other, creating a bigger wave or a bigger maximum at that point. If they are in opposit phase, they'll undo each other either fully or partially. This is called an destructive interference wave.
Constructive interference can be a confusing concept when called interference. It is wave interference that is moving in phase with another wave. This causes the waves to for a resultant wave with a greater amplitude. Destructive interference is wave interference that is moving out of phase with another wave. These waves form a resultant wave of lower amplitude.

Interference
Yes, wave interference occurs for all types of waves.
Another name for it is wave interference.
No. Refraction does. A single wave doesn't encounter interference until there's another wave present.

It "is" neither; however, light interference is related to light's wave-like properties, not to its particle-like properties. Interference is something that affects all sorts of waves.
Constructive interference is in-phase addition of waves, such that wave amplitudes increase.
