The general format below refers to a book with three authors. For a book with four or five authors, you would add the additional authors' names after the first three.
If you are dealing with a book that has three to five editors instead of authors, you would simply insert the names of the editors into the place where the authors' names are now, followed by "(Eds.)" without the quotation marks (as per the example). The rest of the format would remain the same.
