How do I fix my Bluetooth problem with my iPhone 7?

I have an iPhone 7 and I have been using black web wireless head phones. These headphones have been working really well but I had my phone forget the Bluetooth connection with them and now my phone doesn't connect with them. My phone does not even portray that my headphones are on and searching for a connection. I know the headphones still work because I use them with my computer. I have tried restarting my phone and fully charging each device but it doesn't work. My Bluetooth on my phone still works bc I can connect with other devices but these headphones are still not working!

Can the use of a VPN be traced back to me?

If I use a VPN my college's school Wi-Fi, can it be traced back to me? Apparently it's breaking school rules to use one and I won't be using it again but if they know somebody's used a vpn can they find out who? It's on my iPhone X, I'm just wondering if they see my name or anything. I'm not doing anything bad on the school Wi-Fi, it's just that you can't listen to music or watch educational YouTube so when I run out of data sometimes I'll turn on this vpn on my phone to listen to music or do normal school stuff that's blocked for some reason.

How do people around my age ahve money who don't work or go to school?

I'm 20 years old in Chicago, I go to college full time and work full time and my job is the only means of money in my pocket so I'm so confused as to how another able body 20 year old like me in Chicago has money but doesn't work. All they do is party all the time and don't do anything. They just somehow have thousands of dollars but never had a job. I seriously need to know what they do cuz I'm going out busting my back at my job for a check. We discussed this in social science, saying you have lazy able body people around my age not working or going to school all night partying and doing nothing. They just somehow have money. These people have no disability either. Do you think people are lazy and take advantage and lie in Welfare programs to get over on them and take advantage. I feel like you have people out here getting social security disability who don't have a disability they just lied to get free money. Which brings me to how someone is using food stamps but has an iPhone XS Max and is wearing 500 dollar Jordan's with a goose coat. Seems shady to me, you have all the high end material brand things but can't afford food, I'm just so confused.

I'm switching iPhones and services, and I concerned about the process and loss of service (even temporarily). Any tips on how to handle it?

I bought an open iPhone SE to replace an older iPhone, and I'm signing up for a different service. They provide the SIM. And of course I want to port my old number to the new service. But I don't want to cancel my old service before the new one is set up. If I set up the new service before I cancel the old one will I have two functioning phones on the same number for a while? I'm not sure how to handle this and cause the least disruption to my service.

IPhone 7 ringtone and alarm problem?

Recently my iPhone 7 stopped making sound when recieving calls and when the alarm goes off.
When trying to switch a ringtone, they all make the same default sound, and all do not make sound when recieving calls. Same thing with alarms, they all make the same default sound and make no sound when the alarm goes off.
The ringer is on and in full volume, I've restarted the phone, hard reseted it, I've reset the settings to default settings and still nothing solves the problem.
Can anyone please help?

Does this email mean that someone tried to login my account or that they did login to my account?

I read an email i got from instagram febuary 9, saying and i quote "We noticed a login from a device you don't usually use." It then shows me that it was from a device by an apple iphone on mobile safari in Boston, MA on febuary 9 at 11:38 AM. This is NOT ME. I know nobody in Boston, i've never been there either. I'm confused if this meant they actually got into my account which is so creepy. Is there even anything more i can do to find out who did this or protect my instagram account?
