Learn English – Which is right to say: “i went home early last Friday” or ”i came home early last Friday”

The main difference between talk and say is that to talk is to "to speak about, to converse" and to say is "to state something, to affirm or deny something".

I was talking with customer service about my new phone's bad sound quality.
--What did the customer service rep say? Did he give you a new phone?

I find your #2 ungrammatical.

It's legal to say something like, "When did you go to the cinema last?" although I prefer it as in your first example, "When did you last go to the cinema?" Adding "time" to the end of that is not natural English, though.

There are, of course, many ways to end a sentence with "last time", as long as it makes sense in context and (I think) is part of a phrase:

Can we go to the cinema like last time?

Which cinema did you go to last time?

Did you like the movie we saw last time?

Who were you with last time?

And so on. The difference between these and your question is that "last time" is the direct object of the question, "when was the last time ..." and the rest is an adjectival phrase that modifies "time". With the other examples, "last time" is part of a phrase that modifies some other part of the question.
