Is it possible to send bitcoins without paying a fee?
How many confirmations required to ensure a transaction is successful?
Is it possible to transfer without internet?
No it is not posible for you to send money without any fees.
I would say 5-10 confirmations from the miners.
It's not posible to send without internet. (How can you send some data to another server if you're not connected to the internet? [Well yea unless you're in a lan cable with the all of the miners])
