Suppose all the pieces are on the board. Does there exist a position such that
A) one of the players can't make any move (a stalemate)?
B) neither player can make any move (a double stalemate)?

Why does the solution here not work?
This is clearly not reachable from the starting position (because of the bishops stuck on the first rank), but the question does not state the position must be legal.
Here is an example of a 12-move game after which White (to move) is stalemated. All 32 units (pieces and pawns) are still on the board. The original version of this concept game was created by Charles Henry Wheeler, and published in Sunny South in 1887, according to Edward Winter's C.N. 3679. Samuel Loyd is often, and wrongly, given credit.

@Rosie F has answered the first part and @im_so_meta_even_this_acronym's answer proves that it indeed possible with an illegal position. However, I want to focus specifically on legal positions just for fun.
The known maximum number of pieces that can be legally stalemated is 30 pieces. I have two examples.
I found this one in the Die Schwalbe Chess Problem Database..

To answer the second part of your question:
Suppose all figures are on the board. Does there exist a transposition of figures such that both of the opponents can't do any move (a stalemate)?
No, this is not possible. Pieces are simply too mobile for this, so for a stalemate you need to hem them in (like the white queen in @RosieF's answer) or pin them on the king. You cannot use pins for a double stalemate, since that would imply the pinning piece can move and it's not stalemate for the other player. (That piece could be pinned itself, but there's no way to make a circular pin.)
