Electrical issue?

I drive a 2012 Ford Fusion SEL with a 2.5 Liter engine. Here recently a few dash lights have come on and stay on while I’m driving. The door ajar light as well as the parking brake light. When the lights are on I can still drive but I can’t see my turn signal lights (they still work on the outside of the car) and I can’t turn on my ac. I also am unable to pop my trunk. I’ve been driving it with the lights coming on for about 4 days. This morning when I started the car the lights came on as usual but then the car alarm started going off even after I started the car. The only way I got it to turn off was unplugging the battery but as soon as I hooked it back up it started again. I’m at a complete loss about what it could be
