It cannot move on 2nd square if both 1st and 2nd are empty.
That is incorrect. F2 can move without capturing to the 2nd when the first is empty. This is indeed a bit irregular, but I don't think there is anything against that.
The Falconer is FaFaaF (one, two or three diagonal steps). The diagonal version of a Tenjiku Shogi 'area move'. I would not be surprised if this was a Jetan piece.
The soldier can be further abbreviated to ifmW4fsmWfcF. (It is possible to combine different directions on the same 'atom', but not different ranges.)
Tank WjR would be the recommended notation. RjR is not wrong, but all distant moves would be indicated twice if the 1st square was empty.
As I understand from the move diagram the Spy slides, so W2N is correct. Otherwise the D squares would have contained the jump symbol.
Note that the Chu Shogi Lion can also make the two King steps as a direct leap, which is more than a King that moved twice could do. If you just want the double King step it would be KmcaKmcabK.
