The Septuagint is from several hundreds years before Jesus. Some posit that Jesus might have traveled around learning from various spiritual types in his "missing years", so there would potentially be some influence there. The reality is that we don't really have any of Jesus's deep teachings, the stuff he is quoted as saying "the mysteries are not for them" when asked why he uses a lot of parables in the public speeches.

Buddhism was from around 500 years prior to Jesus, Hinduism much further back then that.

That being said, they could have been influenced, in their various flavors, in the millennias after Jesus, certainly! Buddhism especially is really just a set of instructions for personal-awakening, not an actual religion - it's only in combination with other preexisting cultural faiths that it's various offshoots were turned into a sort of religion. There are many Christian buddhists out there!
