Ah, finally, a solution! I didn't think we'd ever get one.
So, it turns out that I didn't consider a possibility of a black piece eating the bishop on its way back... nice puzzle.

Alright well I guess I'll do the next one. It's not very hard, but here it is.
White to Move. Where can white move to force a stalemate and why?
Note: There is more than one possible move to force a stalemate. So give all possible moves to force a stalemate.

White has to make sure that it moves the king to f1 after black moves its king on e2 or g2. Black has no other choice but to move back and forth infinitely, lose the pawn or force a stalemate.
It is easy to force this situation.
1) Move under the pawn.
2) Once the pawn is on f3 and the black king is on the 3-rd row, make sure that your king moves to the same column on 1-st row. Until then keep moving back and forth.
It is a standard situation. King under the pawn = stalemate. This is why in the end game the winning side (i.e. the one that has 1 pawn advantage) is trying to avoid it and the losing side is trying to force it. This happens long before there are only 2 kings and 1 pawn left.

No I said white to move. Tell me the move(s) that white has in order to force a stalemate.
Use proper notation.
Such giving an opening for the sicilian accelerated dragon.
1. e4 c5
2. Nf3 Nc6
3. d4 cxd4
4. Nxd4 g6
For our problem white has 8 moves.
Ka1, Ka2, Ka3, Kb1, Kb3, Kc1, Kc2, Kc3.
Which of these moves can white make in order to force a stalemate.
For each of these moves explain why or why not white will be able to force a stalemate.
Here's another puzzle for you guys.
Play a game where white and black is cooperating to achieve the move 6.gxf8=N mate
This means on the 6th turn white will move his or her pawn from the square on g7 to f8 and turn that pawn into a Knight which will checkmate the black king.
Here's a picture to help show you what I'm looking for.

Kc1, Kc2, Kc3 will all work. Next is Kd2, etc.
Next puzzle is nice, btw, I can almost see myself getting stuck on it just like I did on the first one 
Edit: nm, I didn't get stuck on that one I won't post my answer to give other people a chance.

How can they be wrong when they all lead to the stalemate? Isn't that what the goal is?

They don't all lead to stalemate, that's part of this puzzle.
Edit: I'll give you a hint, only one move leads to stalemate.

to the stalemate puzzle:
K-c3, K-d5 or f3
K-d3, K-?? or f2
K-e2, K-?? or f1-Q
Kxf or K-f1
K-c2, K-d5 or f3
K-d3, K-?? or f2
K-e2, K-?? or f1-Q
Kxf or K-f1
As long as u move K-c2 or K-c3 you can stalemate by moving towards the pawn and aiming for f1 but making sure to minimise distance between the kings (stay on 3rd row until you have to move e2)
And is the knight puzzle possible? because i have spent a while looking at all the possible combinations and have only seen one combo which comes close...
e4 f5
exf5 K-f7
f6 K-g3
fxg2 h6
Q-g4+ K-h7
gxf8=N+ ... (Qxf8)

I'll give you a hint that e4 is not a good way to start things off. The key is obviously that you need to make the move Kd7 at some point in order to have the Knight put the King into checkmate. The other thing you must do is make it so that black can't take the knight. Finally you must find a way that the king can't simply move out of the check.
This one took me about 15 to 20 minutes.
As for the part about the stalemate thing. You are also incorrect. One of your solutions does not lead to stalemate.
If you want a last hint, I'll tell you that there is only one move that can force a stalemate.

Hmm... you are right, c3 is the only move as it forces the black to move its king all the way. Otherwise the black can move its pawn. I didn't think about the black moving its pawn when I wrote my last post. The fact that I haven't played chess for so many years has its consequences
Kc1/Kc2, Kd4
Kd2, f6
Ke1 (no other choice), Ke3
White is screwed.

Ke1 is not the only choice. White can also move Kd1. And a player who doesn't know their chess very well would likely mess this up and move Ke3.
1. Kc2 Kd4
2. Kd2 f3
3. Kd1 Ke3
4. Ke1 f2+
5. Kf1 stalemate.
Now let's look at the same puzzle but with one small difference. The black pawn is starting on f5 instead of f4 one more space back. Explain what makes this puzzle different and how it could change which move or moves white can make to force a stalemate.

The solution is still c3, otherwise the black king can move forward and once it is under the black pawn, the white king will be forced to move to the side, clearing the way for the black pawn. I think f6 and f7 will still lead to the stalemate, but f8 is a win for the black because it will be able to move the king back or move the pawn forward, forcing the white king to move out of the way.

There's two solutions for this one.
An important concept that you need to know is that whether black or white you want to move second and mirror your opponents moves.
Kc2 does not work because black can then move to Kc4.
1. Kc2 Kc4
2. Kd2 Kd4
3. Ke2 Ke4
4. Kf2 Kf4
Now white must move either right or left and white can move to the 3rd row.
5. Kg2 Ke3
6. Kf1 Kf3
7. Ke1 Kg2
8. Ke2 f4
9. Ke1 f3
10. Kd1 f2
11. Ke2 f1=Q+
However Kc1 works just fine. Here's an example of how to effectively prevent white from queening the pawn.
1. Kc1 Kd5
2. Kd1 Ke5
3. Ke1 f4
4. Kf1 f3
5. Kf2 Ke4
6. Kf1 Ke3
7. Ke1...
This is where it becomes clear that black cannot pawn the queen.
7... f2+
8. Kf1 stale mate
_______
7... Ke4
8. Kf1 Kf4
9. Kf2 Kg4
10. Kf1 Kg3
11. Kg1 Kf4
12. Kf1 Ke4
13. Kf2 Kf4
14. Kf1 Ke4
15. Kf2 Kf4
16. Kf1 Kg3
17. Kg1 Kf4
18. Kf1 Ke3
19. Ke1 Ke4
20. Kf1 Kf4
21. Kf2

nice, I didn't think of c1. But ah well, when you are playing, you only need one way of stalemating
Edit: by the way, there is a 3-rd way to force a draw for the white if you play this game at a tournament ;-) I'll let you think about it and if you give up, I'll give you the answer.

If you are talking about mutual agreement on a draw, then you are incorrect. The only forced draw is a stalemate. A draw is not a stalemate. Draw by mutual agreement isn't forced.
jk I know what you meant to say 
But yeah mutual agreement is another possibility.
Am I correct in what you were thinking or did I make a fool of myself?
