Game result went 0-1; I believe he had drawing chances early, and also on diagram 3, where the Philodor Drawing technique may have been used...with difficulty due to his king being cut off a rank. It is definitly possible but I am hazy as to how white draws that 3rd diagram so I probably would have lost there...because white's king can't get to the short side of the pawn I don't believe passive defense works..
I can't belive the first position is a draw, but not the second, black look better as he force an exchange, good thing.
The third, I think white can draw this, but I can't see how, the king is cut from the pawn.
Edit : I think white can draw with something like Kd3 Rh8 then Rh1 to bring back the rook to the field.

I believe #3 is a win for Black. It's quite easy to get to a standard Lucena position, and then Black wins like this:
[pgn]
[FEN "8/2r5/R7/8/8/8/1p1K4/1k6 w - - 0 1"]
[result "0-1"]
[SetUp "1"]
1. Ra8 Rd7+ 2. Ke3 Rd5 3. Ra7 Kc2 4. Rc7+ Kb3
5. Rb7+ Kc3 6. Rc7+ Kb4 7. Rb7+ Rb5 *
