Absolutely. If team A wins the toss prior to the game, and elects to defend a goal as their choice, and team B then wants to receive the ball to start the game, it would be team B's choice to start the second half. If team B then chose to receive, team A would thereby be kicking off to start both halves.

I assume you mean "Where is the spot of the ball for a kick off at the start of the game or the start of the half, or after a touchdown, or successful field goal attempt?" Standard kick of is at your own 35 yard line. Penalty's from previous plays, or an off sides on the kick off, can be enforced on the kickoff, or re-kick, moving the spot of the ball.
