If you're asking if you can use two Apple ID's simultaneously on one iPhone then no, you cannot do that.

You can enter the Apple ID you already have and tap Sign In. If you don't have one, tap Don't have an Apple ID or forgot it and follow the onscreen instructions. Your Apple ID will now be set up. You can find out more about your Apple ID through Apple's website.
