Yes a goalkeeper can kick the ball and score more then one goal into the other net. And he can score from corner kicks as well.
Yes. You can score from anywhere on the field at any time except from a throw-in or an indirect free kick. Also, you cannot score an own-goal directly from a kick-off, goal kick, corner kick, free kick, or penalty kick.

Yes you can. David Beckham from the Los Angeles Galaxy once did in 2011.
no, a corner kick is awarded to the attacking team. the purpose would then be an opportunity to use a set play to try to score.
It was Chelsea's first corner kick of the match which came very late in regulation; the goal was scored by Drogba.
You try to score goals, they have positions, if it goes out from the side its a throw in, if it goes out behind the goals and the defense did it, its a corner kick, and if the offense did it then it's a goal kick.
