Alternate ways of changing iphone password?

So I dropped my phone and a large portion on the right hand side doesn't respond to touch. My password includes numbers on the side that you can't touch, so I've been getting in through touch ID. However, if it turns off or I get locked out of touch ID it will make me put in my password which i can't do. Is there any way to change my password other than in the settings>touch ID and password because that requires you to put in your password which I can't do.

Why isn't my iPhone using my new Apple ID?

I just created a new Apple ID but my phone isn't using it even when it says it is in settings, and at the bottom of the Apple and iTune's pages. I tried updating my apps but it asked for my password from my old ID? I need to creat a new Apple ID because in my old one it started asking for credit card information which I didn't want to put in anymore and without that I couldn't buy free apps or update them and sadly the none option is no longer available.

Iphone 5s won't pass apple logo and won't restart?

I hold the power button and then my phone will turn on and go to the apple logo, then turns off. Even charging it will turn it on to the apple logo then turn off. I've tried restarting it (pressing the power button and home button at the same time) and it'll turn on, but turn off again.

Can't set up 'hey siri'. But siri works holding the home button

IPhone SE, 2 months old.
Microphone is fine, everything else works, no case blockages. It does respond when I press and hold the home button, but not when I set up the 'hey siri'. I have no disruptive cases, I have restored and restarted my phone several times and have updated it.

Found a lost phone on the way to practice, 30 minutes later was found by police

I went home and saw a black iPhone on the side of the road. I took it and went back home to change and get my gear for practice. I left home and go to school for practice planning to return it after practice. 30 minutes when all of us were practicing, The police came and checked our bags. She found the iPhone and told me that I won't be in trouble. She took my basic info and gave me a police report number. Will this go to my records? I'm planning to join the military after high school.
