1. No, promoted elephant and knight cannot promote further. 
2. I think knight and camel have same value or the camel is stronger. The reason for knights promoting to camels is their movement, knights are (2,1) jumpers and camels (3,1) jumpers. 
3. I must have been sleeping when I wrote this. I'll upload the page as soon as possible. En passant is NOT in this game. :/ 
4. As in shogi, you can't mate with a dropped pawn. I'll include this when I upload the page. Stalemate is draw, as in FIDE chess. 
 
Thank you for the comment! 
Hope you'll enjoy playin'!

According to http://taikyokushogi.hp.infoseek.co.jp/taikyoku.swf, this mark -|-|-|-> means 'may jump over three pieces on its way'. In this link,  get the piece that starts at 20 32 out on the board and look at the forward-diagonal moves: it may move four spaces into the opponents start row, jumping over three pieces- or one, or two, jumping over one, or three, jumping over two.

According to http://homepage.ntlworld.com/gpjnow/VC-GM.htm,
a (0,3) leaper
is called a threeleaper.

David,
I agree. I'm working on a better solution, this is only the first try. I find most 3d chess variants too complicated, I simply was trying to make gameplay easier. I am (like I said before) working on - my new version (not posted yet) has got 48 pieces, that is 15% (still too low) and it has got the mace, the mace-bishop, mace-rook and the rook-bishop.

Daniil, 
I'm glad you asked. Yes, pawns do promote although I forgot to mention it. Their promoted form is the gold, as in Shogi.
The idea about the XS-chess pawns is that it is the shogi pawn (straight forward, capturing as it moves, promoting to gold), the xiangqi pawn (straight forward, captures as it moves, can move and capture one sideways upon crossing the river) and the chess pawn (one squere forward, captures one diagonally, can move two squeres forward on it's intial move. Can capture En-Passant forward (as the chess pawn only can move forward)). That becomes the XS-chess pawn: Moves one squere straight forward (all variants), captures as it moves (xiangqi, shogi) or one squere diagonally forward (chess), can move and capture one squere sideways after it crosses the river (xiangqi), can move but not capture two squeres forward on it's intial move (chess), promotes to gold (shogi) and can capture En-Passant forward only (chess) as the xiangqi pawn (who can move sideways after crossing the river) can never move two squeres at once, only the chess pawn can (and only forward). As pawns can move sideways after crossing the river, they can always move, no matter what. All those 'extra effects' makes the XS-chesspawn much more powerful than normal chesspawns, normal shogipawn or even normal xiangqipawn! I still say it is worth one point but in fact it should be three or four points...
