The good thing about stipulation problems is that computers are of no use.
You have to use the God given brain.
The first one is easy.
White to move and mate in 5.
White can only move his King.
The second is harder and brilliant.
(except for Green Paladin...he solved it when it appeared on here 4 years ago.)
White to play and mate.
White can only move his Bishops
The Black King and pawns can move, but White can only use his Bishops.
A clue: Just to whet your appetite and you pull you in.
You need to free the h3 Bishop so you have force Black to play e6.
and then force Black to capture on f5. (Let Zugzwang be your weapon.)

"[T]he difficulties appeared to me in the nature of a challenge, which it would be pusillanimous not to meet and overcome. So I persisted, and in the end the work was finished, but my intellect never quite recovered from the strain."
Good puzzle, GP1!
