The 1611 King James Bible included 14 books in its Apocrypha section.

What those books were

The list commonly counted as Apocrypha in the 1611 KJV includes books such as Tobit, Judith, Wisdom, Ecclesiasticus, Baruch, 1 and 2 Maccabees, plus several additions to Esther and Daniel.

Small counting difference

Some people count it as 15 by treating “Baruch with the Epistle of Jeremiah” as two separate books, but the KJV’s own Apocrypha section is typically listed as 14 books.

So the short answer is: 14 books.
