Many books have an author and a co-author. The co-author is a writer who works with another writer on a book. They may both be considered co-authors or one may be considered the main author and the other co-author.
Dave and Larry wrote a book together, Dave is the main author and Larry is the coauthor.
The word coauthor is a noun. The plural noun is coauthors.
It means that more than one author wrote a book/article together.

no.
A book can have more than three authors-- a book can have as many authors as contributed to the book. However, most publishers will ask to limit the authors' names to the fewest, with secondary authors listed on a front page.
According to the sources I've found on a quick search, you should hyphenate 'coauthor', i.e., it would better be: "co-author".
Generally co-author should be hyphenated, but the relaxed rules of modern times often present coauthor as one word
Examples of co are cooperate, coworker, coauthor and so on.
