Sure but not with technology we have today.

if yes how long would it take?
Depends on what technology you have, how big a planet you want and what conditions you're willing to accept when you're done. If you want low gravity lots of heat it would take far less time than if you want a big planet that is fairly cold.
Anywhere from decades to centuries is imaginable. With Star Trek style superscience or other magic it could be done in seconds.

Other planets, or with magic/superscience alternate dimensions.

Probably not, certainly it would never be practical to build such a thing.

3. lets say humans want to leave earth for a certain reason, how would we do it?would we build a ship large enough for 6billion people or go back and fourth untill every one gets to the place?
There's no currently anywhere to escape to.
Neither of those solutions sounds ideal. The first puts all your eggs in one basket if the unproven giant spaceship fails everyone dies. If you build one small ship and go back and forth you need a huge amount of time.
I'd build lots of battleship sized vessels and send them off in waves.
