You can't get a T Mobile service on a phone that's not T Mobile unless you get it unlocked. Once the phone is unlocked, you can use your T Mobile SIM card on it or any other GSM SIM cards worldwide.
Only if the T-Mobile phone is unlocked. If the T-Mobile phone is still locked, only T-Mobile SIMs will work.
Yes it is free to call a prepaid T-Mobile phone from a T-Mobile phone but instead of worrying about the bill just change the plan to a unlimited plan.
You should put that T Mobile phone in your name now. You might want to get your own phone number for it. Yes, you can just buy minutes.
