In game 1, Black's play seems to go a little funny around move 33; up to that point I was willing to believe it was a pro game.
Game 2, the move 13/15 combination seems to put a lowish upper limit on the strength.
Game 3, the initial sequence with the probe is something you typically see from high-level players. Move 28 looks funny to me, but not enough so I'd definitely call it bad. White seems to have tried to win the capturing race by creating a big eye which takes some reading ability, but misreads do happen at every level. Not sure about this game.
Game 4, move 45/47 looks odd. Other than that, some signs of thought.
Game 5, move 9 looks bad; move 43 seems a bit overconcentrated and surrounds an open skirt; the sequence at 224 shows some reading problems.

The third one looks really like pro game, but i don't think pro will mess up the game so early

1. looks like a bad shape. Pros would probably make the solid connection at P14 instead. But fixed it for black. R18 might have been better. seems wrong -- why would black strengthen the stronger right side at the expense of the weaker left side? should have switched places with . looks a bit odd too. F15 or even E13 seems the shape here. And black's misreading the sequence starting with is unimpressive. White's handling of the lower-left corner seems somewhat timid (e.g., why not at D3?) OTOH, both players demonstrated some skill with moves like and . Finally, I don't think a pro or high dan player would have played the last few moves like black did before resigning.

2. It looks like neither player saw anything wrong with the lower-right corner after .

3. Up to this could have been a pro game. However, white needed a move at C17 or B13 to defend the corner. White might have misread the corner or the capturing race (overlooking the combination?), which is somewhat uncharacteristic of a pro. But white's resigning without playing out the sequence seems to suggest he is at least a high dan.

4. is wrong. could have taken advantage of the mistake of by continuing pushing on the 4th line. Black #159 at P7 would have captured at least the two white stones; or better yet, O6 would have ensured the capture of the three white stones and the escape of the four black stones.
