As noted there are two that seem to be from two Indian philosophical schools or perhaps ancient religions I'm not familiar with, and a some Manichean writing too.

Of course, the extent to which "Orthodox Buddhism" itself has been influenced by other religions is open for debate. It's often a prickly debate. There are some who see a lot of Zoroastrian influence in some strains of Pure Land thought; it's hard for me to say one way or the other.
