#1 - Both are OK.

#2 - Both are OK. 2-1 is just a bit more expressive or emphatic.

#3 - They are similar, but 3 indicates having met someone for the first time, while 3-1 indicates having met and seen someone more than once.
"Tell me" is more like a command, while "excuse me" suggests that you have interrupted some ongoing activity and are apologizing for doing so.

"Love" is more emotionally extreme than "like."

"Meet" is more likely to be used with a new acquaintance, while "see" is more likely to be used with someone you already know and see repeatedly.

I hope this helps. Thanks for asking.
