I've moved both of your questions off the other thread. When you are not responding to someone's post, you need to start a new thread. That way our members will realize you are asking a different question.
What kind of tortoise do you have? How old/big is it?
Two males will eventually battle until one is dead...
A single male and a single female will be making the female's life hell on earth...2 or 3 (or more) females w/ one male will be OK, because he'll be spreading his "reproductive glee" around between them about equally, so no one gets all stressed to death.
OTOH, a tortoise can be very happy living solitary, as in the wild they're solitary about 99% of their lives.
