Yes.
Commas are placed before, after, or around a noun or pronoun used independently in speaking to some person, place, or thing:
Not usually : "Thank you for listening to me" does not need a comma. However, if you write their name afterward ("Thanks, Fred."), you need a comma after thank you.
No just after their name.
When you address someone directly, you offset their name or pronoun with a comma(s). "Joe, please give me a hand." "I'll be there in a minute, Mom." "Thank you, Peter."
No, the sentence "Thank you John" is not grammatically correct. It should be written as "Thank you, John." Adding the comma after "thank you" separates the person's name as an interjection in the sentence.
No, you do not typically put a comma between a person's last name and their suffix (e.g., Jr., Sr., III). You would write the full name without a comma between them.
You should put a comma before a person name if you're talking directly to them. ex- Please come here,Lily.
It depends on the application, but if you're referencing at the end of an email or letter, it would come after. Example: Thank you, *insert your name*
If your question is the following then there should be no comma: Should there be a comma after "a man by the name of _______"? No comma is needed.
The style manuals say that anytime you address a person directly, their name should be set off with commas. The correct syntax is: Thank you, John. Hello, Susan. Don't look, Sharon!

Words within a sentence, after a comma or semi-colon, are not capitalized, except where the direct quote (quotation marks) is used, or for a proper name.
