The Old Testament books to which you refer—know in the Orthodox Church as the “longer canon” rather than the “Apocrypha,” as they are known among the Protestants—are accepted by Orthodox Christianity as canonical scripture. These particular books are found only in the Septuagint version of the Old Testament, but not in the Hebrew texts of the rabbis.
These books—Tobit, Judah, more chapters of Esther and Daniel, the Books of Maccabees, the Book of the Wisdom of Solomon, the Book of Sirach, the Prophecy of Baruch, and the Prayer of Manasseh—are considered by the Orthodox to be fully part of the Old testament because they are part of the longer canon that was accepted from the beginning by the early Church.
The same Canon [rule] of Scripture is used by the Roman Catholic Church. In the Jerusalem Bible (RC) these books are intermingled within the Old Testament Books and not placed separately as often in Protestant translations (e.g., KJV).
