Q.Christmas Cactus and Snake Plant
I came across one sight that said you could plant cacti and succulents together. I wondered whether a Christmas cactus and snake plant could be planted together, or is it too much of a stretch putting them both in the same container?
Also, I was given what I believeĀ is called an elephant plant that was going to be thrown out. The person who gave it to me didn’t know its name. I researched pictures on the Internet; the leaves are huge on this plant. I was able to bring it back to life. It has layers of vines circling around the base of the plant. This is the best way for me to describe it. Does this plant have to be repotted, or is it best to leave it in the same pot? I have never owned a plant like this before, especially such a huge one, so I am new in how to care for it.

Christmas cactus and snake plants have similar water and light needs, so they will be fine planted together.
I believe the plant you have is a Elephant Ear Philodendron or Selloum Philodendron. You can repot it if you like, though they are pretty forgiving of a crowed pot. Do not trim those viney things at the base, they are aerial roots. I would recommend providing something for these roots to cling to, like a pole of some kind.
