A pun is 

1. 

the humorous use of a word or phrase so as to emphasize or suggest its different meanings or applications, or the use of words that are alike or nearly alike in sound but different in meaning; a play on words.

Only one of your sentences has a word which relates to the subject but is not the word you would expect to see.
