How to tame my rabbit

Question
I had my male rabbit donnie since he was three weeks old he is a year old and six months. I bottle fed him and played with him daily. He is pretty much used to me. I recently found a female rabbit in my backyard, and i took her in nurse her back to health. I put both of them in the same hutch and they just bonded. She is sprayed and he is also.I want to take donnie out to play in the yard, but i am afraid he will run away. How do i take them out without making them running away? Rosa was really easy to catch, she was hungry and really skinny i fed her and i brought her to a vet. But i will like to let them run around my big yard, without making them be in the hutch all the time. The hutch is big and alot of room to run around, but i want to take them out.
Also How do I teach my rabbit their names? I want to call them by their names so that they will come or stop when i call them.

Answer
hi shan -i'm afraid rabbits don't answer to being called a name they don't respond like a cat or dog.
if you take them out to run around you must have either a fence they cannot jump and no holes in it but  you can buy outside runs which keeps them contained but they can still run around.
