Dear Yury,
Nice contest for TheChessWorld!
Though it took me (2+ hours) more than I thought sending the solutions to the interesting puzzles.
The system didn’t accept longer comments, but the variation details are necessary for completion. Finally, decided to send answers in two parts and hope you’ll able to get it. Keep us posted!
Thanks,
Arjoe

2.Rb3-Kxc8 Rd3 a1=Q Rd8#.Rb3 preparing for discovery check from the promotion a2,forcing the king to take the knight.Rd3 tempo for a mate.
3.Rf6-Qg8 Rh6+ Qh7+ Rh6xh7#.Bishop occuping the a2-g8 diagonal, the king on the edge of the board,rook on the 7th rank.limit the square for the king, another rook to reinforce the checkmate pattern Rf6. the only defense is Qg8 but can’t stop the checkmate.
4.Rc4-Nd1 Ba3-Nb2 Rc1#.Rc4 can’t be taken by knight because the king forward to Kc3.Preventing the c3 knight goes to d1. then starting maneuvring the dark bishop to a3. no moves for black. outpost the lonely knight to move along.
5.Qd4+-Ke2 Ndc3+ Kf1 Qg1#/ Qd4+ Kc2 Ne3+ Kc1 Qd1+ Kb2 Nc4+ Ka2 Nc3#.Two tricky knight and Queen combination a kind of hard thing to do, but proper move order lead to checkmate pattern. 😉

Position 5:
The correct move for white here is 1. Nc3. If black plays 1… Bc1, white plays 2. Qd4+. Black is forced to play 2… Kd2, which is followed by Qe2#. If black instead plays 1… Bb2, White plays 2.Qd4+, forcing black to play 2… Kc2, which is followed by Qd1#. If black plays 1… Bb4, white should play 2. Qd1, forcing black to play 2… Ke3, which is followed up with Qe2#. If black moves his bishop elsewhere, White should play 2. Qa2 Now, black can not stop 3. Qe2#.
If black plays 1… Kd2, White should play 2. Qd2+, forcing 2… Ke3, which is followed up by 3. Qe3#.
Just a reminder that I have 3 comment posts of notes, due to the symbol limit, and the fact that I had more lines to go through but no space. (I saw no rule against this, so I am assuming that this is allowed. If it is not, please let me know ASAP and I will try to condense it into one comment).

Position 2:
White should play 1. Rb3. If 1… Rxc8, the continuation is 2. Rd3, then Rd8#. Black’s only other possible move choice is a1=whatever. This is followed up with 2. Ba5+. Black’s only move is 2… Kxc8, which leads to Bh3#.
Position 3:
White’s correct move is 1.Ra2 If black plays 1… Qb7, then 1.Rh2 is mate. If black plays anything else, then the correct move is 2. Ra8+, The queen is now forced to block, which white will the capture with the Rook (wherever it goes), which will be mate.
Position 4:
White’s correct move is 1. Rc4. If Black plays 1… Nxc4, then white should play 2. Kc3, followed by Bxb2#. If black plays 1… Nd1 or 1… Na4, then White should play 2. Rb4, followed by 3. B(x)b2#. If 1… Nd3, the correct move for white is 2. Ba3 followed by 3. Rc1#.
Position 5 continued in next comment
Position 1:
White should play 1. Qc1 if 1… g3 is played, then 2. Qxc8# is mate. If 1… d2 is played, 2.Qc3 is the correct response for white. Here, black is forced to play 2… g3 (his king can’t move, and the bishop can not block), which is then followed by 3. Qxc8#. If Black moves his bishop anywhere on the a6-c8 diagonal, white follows up with 2. Qf4. Black can not stop white from playing Qh2#. If 1… Bd7, White plays 2.Qc7, followed by either 3. Qh2#, or if 2… g3 is played, 3. Qxd7#. If black plays 1… Bh6, white follows up with 2. Qe3+, forcing 2… g3, which is followed up by 3. Qxe6. If black plays 1… Bf5, white plays 2. Qf4. This is either followed up by 3. Qh2#, or if black plays 2… g3, Qxf5#.
