Thank you,
*insert your name*
Yes, you do. For example, "Thank you, staff and parishioners."
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.
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."
Not necessarily. I want to thank you for helping me last night. A comma would wrong here. "Thank you," said Sam. There is a comma here, but it is not because of the words "thank you." You would write: "I want ice cream," said Sam. Thank you usually stands by itself or with an appellation. "Thank you, Sam!" In this case, the comma is there to set off the appellation, not because you used the words thank you. For example, you would write: "Go screw yourself, Sam!" or "Sam, thank you so much."
An Oxford (or serial) comma is used right before a conjunction in a list.For example:Without Oxford Comma:I would like to thank my parents, my acting coach and God.With Oxford Comma:I would like to thank my parents, my acting coach, and God.

Yes, you should use a comma before "Jr." when writing a person's name to separate the person's last name from the suffix. For example, "John Smith, Jr."
The comma should come before the word "but" when it is used to separate two independent clauses. For example: "I wanted to go to the store, but it started raining."
