Yes. Most nouns don't differentiate between singular and plural, but たち does make this plural. Similarly, 人たち is also used for "people," with the たち making it plural.
You won't see it very often except for with pronouns, like for example, わたしたち (us/we) or あなたたち (you all/you guys). ら can also be used in place of たち in the case of plural pronouns.
