weird stuff I like your questions Johann.

This is probably a very silly question, but that does not seem to have stopped me in the past.If photons could cancel each other out, where would their energies go?

*In the region where they interfere destructively* there are no photons. But if you start from two beams of light and you make them interfere (example: two opposed laser beams), there will be regions of destructive and regions of constructive interference, and the total number of photons won't vary.

This is a quantum mechanics question; photons are quantum mechanical particles.The answer is that the photons' wavefunction will essentially bend around the points where the interference occurs.This is actually almost exactly the same as the dual slit experiment.

Two waves can only annihilate each other perfectly if they start at exactly the same point at exactly the same time with opposite phase. In the real world, there's no photons emitted in the first place like that.

If two laser are pointing to each other and two photons are generated in antiphase at exactly the same time.Are you saying that this is not possible?
