When using adhesive, I was told u can slide the panels into position, and you are NOT suppose to lift because it could cause airpockets. My question is can you still get airpockets in the adhesive if you slide it too much?

You should be alright if you adjust your panel when the adhesive is in its wet stage. You better have in adjusted before it starts to harden though. If you move it after this point you may have to re-do it. Most brands give you a long window to adjust panel for fit.
