1991 Dodge Stealth ES, Weird noises and issues.

[StealthyMcqueen]

Hey guys! So I've been trying to figure out what the hell is up with my Stealth. I've attached some videos and am wondering what the ticking noise is, what that squeaky noise is, and why the car can't stay on for more than 5 minutes.

Some more info:
-New radiator
-Timing belt was adjusted a few months ago
-Fuel pump relay on passenger side door is working fine.
-Oil change was done about a week ago.

Issues:
-Gas gauge reads empty even though the tank is full.
-Car idles roughly, weird thump noise coming through the exhaust. (Video attached)
-Squeaky noise coming from the timing belt/water pump area. (Video attached)
-Weird ticking noise coming from somewhere around the manifold. (Video attached)
-Cars lock all doors button does not work.
