No, keep the same one.

Is there something wrong with your old one? Then no.

If you have backed up your icloud with that apple id then you should have no problem transferring your personal stuff. If you know the password then its best if you hold on to that id for the new phone

Nope you don't have to you can use your old one and transfer all your personal stuff from your old Iphone to your new one

No you will not need a different apple ID when you turn the phone on for the first time and go through the setup it will ask you whether you have an existing Apple ID or would like to create one. Simply put in your existing Apple ID and anything you have backup on iCloud will download if you want it to.
