insisted and said

"said insistently" or "said loudly"

Truly this man

Here "this man" refers to Peter. The speaker probably did not know Peter's name.

he is a Galilean

The man could probably tell Peter was from Galilee from the way he talked. (See: rc://en/ta/man/translate/figs-explicit)

Man

Peter did not know the man's name. He was not insulting him by calling him "Man." If people would think he was insulting him, you could use a culturally acceptable way for a man to address a man he does not know, or you could leave out the word. See how you translated this in Luke 22:58.

I do not know what you are saying

"I do not know what you are talking about." This expression means that Peter completely disagree with the man. AT: "what you said is not true at all" or "what you said is completely false" (See: rc://en/ta/man/translate/figs-idiom)

while he was speaking

"while Peter was speaking"

a rooster crowed

Roosters often crow just before the sun appears in the morning. See how you translated a similar phrase in Luke 22:34.
