The Editing Policy covers all the permissible edits to articles you didn't create. One of them is categorization, which also encompasses bringing articles into compliance with the Categorization Policy.

To answer the last question first, yes, unique ships go into the nearest applicable category. As for the minimum, technically it's two, but realistically at least three. If all the articles in a single category are by a single creator, it's best if there are more rather than fewer.
