The search starts when the player reaches the area where he believes it is likely to be.
I would say 2 was not searching initially, 3 was.
I would suggest Player 1 is covered by 18.2a(1)/3 - Failure to identify ball
Thanks for that guidance - though I am not sure why you would rule on 2 and 3 differently. In both cases a player is heading to the area that another player has told him his balls lies - but on the way to that area casually checks in the rough along the way - both looking for other balls and just checking in case the player has got the area wrong. Because if the ball cannot be found in the area identified for the search the player will most likely walk back along the way he has come through the rough (Scenario 2 more specifically but also likely in Scenario 3).
I have read your rule decision suggestion for Player 1 and yes - that would work. Player 1 (Eagle-Eyes) was me. I should have positively identified what I thought was my ball before starting to help Player 3 look for his in the trees - because as soon as I looked and spotted what thought was my ball my 3mins had started. That we found Player 3's ball very quickly (as I was correct in my identification of where Player's 3 ball was likely to be) I was able to realise quickly that what I thought was my ball wasn't - but spotted it almost immediately a couple of yards further on - and within the 3 minutes. But if I hadn't - then back to the tee for me
