It's generally not a good idea to mix breeds of tortoises. Each breed is apt to get different diseases and each is immune to different diseases. This means that even if a tortoise is not ill, it can transmit a disease to another tortoise that could become ill.

It depends on the size of your other Tortoises , and if your Tortoises are healthy, I have 4 different types of Tortoise together and they get along great, but I made sure they were all wormed and healthy before I put them together. They are all close to the same size. Also protect them outside from other animals...
