Would Earths atmosphere get blown away if we would hit a gas cloud in space?

No.  The densest nebula have about 10^4 particles per cm^3.  The air you are in right now is round 10^19 particles per cm^3.  It's like a mosquito slamming into a mountain.  We would definitely notice something on the space probes which monitor the environment around the Earth. We might also get some pretty cool aurora displays, but at night the nebula would probably be barely to totally unobservable to the unaided eye.
