Firstly, periods and commas always go inside quotation marks, even single quotes.
Example: The sign changed from "Walk," to "Don't Walk," once the light changed.
She said, "Hurry up."
Example with single and regular quotation marks: She said, "He said, 'Hurry up.'"
The placement of question marks with quotes follows logic; if a question is in quotation marks, the question mark should be placed inside the quotation marks.
Example: She asked, "Will you still be my friend?"
If the quote wasn't a question, the question mark goes outside of the quotations.
Example: Do you agree with the saying, "All's fair in love and war"?
When you have a question outside quoted material AND inside quoted material, use only one question mark and place it inside the quotation mark.
Example: Did she say, "May I go?"
Every time a new person speaks, it should be a new paragraph. Any introductory information related to the quote, either before or after, is linked to it with commas.
