Vid 1 and 3 are just normal noises, its just excess air pressure in the intake system between the turbo and the engine. The noise is just the extra pressure releasing back through the turbo, like i said, completely normal, nothing to worry about.
The 2nd vid, i noticed some surge, thats the rapid ch-ch-ch-ch-ch noise when accelerating. That can potentially damage a turbo if it happens a lot. There are cures for that. The cheapest is to get what most call a wicked wheel, its just a different designed compressor wheel. That will cure surge most of the time. Some times it wont though, and in which case the only other way to cure it is to get a ported intake housing.
A wicked wheel costs about $60 from xtremediesel, and a ported housing is about $450.

Yeah, I'd probably feel a bit drained after firing twice in rapid succession.
