No — castling is not allowed if the king is in check, would cross over a square that is attacked, or would land on an attacked square; castling is also lost if the king or the chosen rook has previously moved (see pages 6–7).

You may capture en passant only on the very next move immediately after the opponent’s two-square pawn advance (see page 5).

When a pawn reaches the furthest rank it must be exchanged immediately for a queen, rook, bishop or knight of the same colour (the choice is not limited to captured pieces); you cannot promote to a king (see page 6).

Yes — except when adjusting pieces after announcing your intention, if you deliberately touch one of your own pieces you must move the first touched piece that can be moved, and if you deliberately touch an opponent’s piece you must capture the first touched piece that can be captured (see Article 4, page 7).

Stalemate is a draw: the game is drawn when the player to move has no legal move and his king is not in check (see page 8).

A player having the move may claim a draw: for threefold repetition either before making a move that will produce the repetition by writing the move and informing the arbiter or after the position has just appeared; for the fifty-move rule the claimant must write the intended move and declare to the arbiter or claim once the 50 moves have occurred; incorrect claims have specified penalties and the clocks may be stopped when making the claim (see page 13).
