they annihilate each other
I'm guessing you're talking about Transverse waves? eg. ~ Waves consist of two parts - a crest and a trough. The crest are the high points, and a trough is the low points. When a crest meets another crest, the wave is amplified, causing constructive interference (the crests add to each other). The same thing occurs when a trough meets a trough. However, when a crest meets a trough, the wave is diminished, causing destructive interference (the crest and trough cancel each other out).
false
The amplitudes cancel each other out so the medium is at its base level, however the two waves are still in existence and will continue on their courses despite the apparent annihilation.
Depends where. If a peak meets a peak, then the amplitude of that peak will increase. Same with troughs. However if the waves have the same amplitude, and a peak meets a trough, they will cancel out, and you will be left with a dead spot, not affected by the wave.

1) Crest of one wave meets the crest of other wave OR Trough of one wave meets the trough of other wave.

The Seine river is running trough Paris and it meets the sea at Le Havre
Constructive interference which theoretically would result in a 6 amplitude as long as the frequency and wavelength of the 2 waves are the same.
