Q: Multiple problems with recently purchases used car

"I purchased a used car and it has quite a few problems: 1. The front passenger power window switch doesn’t work. However, I can open the window through the driver side controls. The passenger door lock/unlock does works. 2. The seat belt lights for both the driver and passenger come on when I start the car, but otherwise they do not light up if someone's seat belt is off when I’m driving fast. 3. I tried to start the car and held the key in the starting position for 1 ½ seconds. The engine turned, car turned on, but it stalled within 3 seconds. I then tried it a few times more and the same thing occurred. But I noticed that if I held the key down longer, the engine would stay on. 4. The car came with 2 keys, but only one works. The 2nd is like a valet key (with a transponder chip) but doesn’t fit. 5. The rear left speaker is broken. When the bass is on med/high, it rattles. 6. There is a crack and hole in the driver’s leather seat. 7. The dashboard/panel light (near the gear selector - the automatic transmission) is extremely dim and the red indicator that should move when changing gears, is stuck. Can you tell me what to do about some (if not all) of these problems to fix them. Thank you."
