If a batter hits the pitch, either fair or foul, with all of one or both feet completely out of the batter's box, he's out. The ball is dead, and no runners can advance.
no because it will be considered a dead ball
batter (cake batter and baseball batters)
"The crowd cheered as the team's star player stepped into the batter's box."
No the ball is dead as soon as it hits the batter, no runners may advance more than one base.
yes, the ball is not dead on a walk, the batter is free to try to advance to second and risk being put out
The batter
It has to be okay. The batter isn't allowed to step anywhere else while he's batting. If you're talking about the chalk lines around the batter's box, yes. They are a part of his boundaries and he can touch them with his foot.

no. the batter can stay in the batters box as long as they dnt move when someone is stealing third base. if the batter tried to block the catcher tho by moving, the bater is out. if the catcher hits the batter and the batter is still standing in the batters box, and the catcher throws to third base and the third baseman tags the runner the runner is still safe.
The batter can make an attempt to reach first, but if the ball is fouled off by the batter, the batter is out (strike out).
batter is out, runners do not advance
Ball's dead and runners can't advance.
