Strictly speaking, homonyms are two or more words that are spelled the same, pronounced the same but have two different meanings. For example "bat" meaning (1) a piece of equipment for cricket or Baseball etc, and (2) a flying mammal. The requirement of the same pronunciation is sometimes relaxed.
To give a homonym for a word you require a meaning assumed by the questioner. Otherwise, all that can be said is that the homonym is "minute".
Minute is a homograph, as it has the same spelling but different meanings depending on the context. It can refer to a unit of time (minute) or something very small (minute).
Words such as "minute" that are spelled the same but have different meanings and pronunciations are called homographs.
