Answer 1

Answer:

Mr.: Used for Married and Unmarried Men

Answer 2

Answer:

Mr: for men, regardless of marital status, who do not have another professional or academic title. The variant Mister, with the same pronunciation, is sometimes used to give jocular or offensive emphasis, or to address a man whose name is unknown.

"Mr" is used with the name of some offices to address a man who is the office-holder, e.g. "Mr President"; "Mr Speaker", see "Madam" below for the equivalent usage for women.
