You can have two queens. You could get the second queen if one of your pawns makes it all the way across the board.
A fully set up chess board has, 2 Kings, 2 Queens, 4 Rooks, 4 Knights, 4 Bishops, and, 16 Pawns.
You put them behind pawns..
You cannot do this. The maximum possible is 5 queens and 5 knights without clashing. A solution to that would be: Queens on a7, b2, c6, d3, e1 Knights on f8, g8, g5, g4, h5
The queen can be on any of the 64 tiles one a chess board. That is to say that by moving diagonally or laterally there is no place on the board that the queen can't get to given enough moves.
Yes, even the Queen, the most powerful piece on the chess board may be caprtured by any other piece, even the lowly pawn.
No. Only pawns can turn into queens once they have successfully reached the opposite end of the board.
32 Or 26, if you discount the 4 rooks (castles) and 2 Queens as "men"
64 squares are on a chess board.
