How many posts do I need to make?

Three posts is the standard. You largely choose the format yourself — reel, in-feed post, story set, carousel — as long as it fits the brief and how you normally post. An ironman who suddenly makes cringe fitfluencer content stands out, and not in a good way.

One guideline: at least one post must be "lasting" (in-feed or reel), the rest can live in stories. Stories disappear after 24h, and a collab needs to remain findable for the brand after the campaign too.
