Well I think Tobirama would like me, cause of my attitude, conviction, and overall loyalty to him and in general. However, Hidan (my other fav) doesn't really like anyone so I'd say no for him
No, Itachi would shrug you off all the time like he did Sasuke.
But he wouldn't poke you in the head, he'd just substitution justu out of the area once he noticed you were there.
