He partially becomes a hollow in episode 19, but actually is first taken over by it in episode 59.
He first becomes what they call a vizard beginning in episode 123 and ending in episode 125. That's just where they have the mask. He becomes a full out hollow later in the episodes in the 200`s when he fights an arrancar in Hueco Mundo
You could say that it was in Episode 19, when he becomes one in the pit (partially) or it could be in Episode 59, while Ichigo's fighting Rukia's brother. I'm not too sure about the first one, but he definitely knows he's connected to the hollow in the 59th episode, since he talks to it. Sorry if this isn't the answer you're looking for.
Somewhere in the 230's when, well if you want me to spoil it, when hes fighting Zongetsu, his zonpakutou. But if you watch all of the episode, he doesn't stay like that for very long. He also almost becomes fully hollow when he was training to control his hollow mask and another time when he trys to become a soul reaper to save Rukia from execution.
the episode 271 is when he becomes a vasto lorde
Inner Hollow Ichigo made it's debut in Episode 39.
we don't actually know, but Ichigo finds out that she already knows in episode 115. so it had to be somewhere in between then and his fight with Byakuya.

Ichigo's "Hollow" is a Homo Sapien Sapien.
"Hollow Ichigo."
Yes he can. Just by going into bankia form and summuning his mask allows him to go "Hollow" But he does need the hollow inside him to agree with loaning ichigo his power as well and ichigo has to wiat a few minutes in between each "Hollowfication"
probably about 3 episodes..or more...okay maybe 4 tops..
if you are up to date with the episodes out you will have seen a full body transormation into a hollow when ichigo was overtaken and lost control whilst fighting with murama however he did push back the hollow form and turn back to normal
Ichigo's hollow doesn't shed tears at all.
Due to the fact that hollow ichigo's powers haven't been fully demonstrated or explained, we do not know
