Aleph, Ayin and Vav/Yud

Pic 1) I don't recall his exact words but I seem to remember R Shtern in Mishnat HaSofer saying that if both nekudot in the Aleph touch at the same place (ie like and X) then it's a major problem - I think he may have been machshir bediavad and I know others are but can anyone shed some light for me? Pic 2) how far does an Ayin have to go to be meshane tzura? This one could almost be a tZadi peshuta - I reckon this one may still be ok, but it's close...? Pic 3) for me the yud and vav are too close even for a tinok. Some may argue since they're slanted and the vav is a bit lower then a tinok can still help. Thoughts?
