my car was running perfectly fine yesterday, went to go start it this morning, and it sounds horrible. Readings attached, any help would be greatly appreciated! Thank you!
If you add Model and Year details, you will get some help ......

Welcome to the forum. Looks like we have the same scanner. Xtool Bluetooth? I recognize those screenshots.
By chance was your car parked outside in the rain? First thing I'd check, considering multiple misfires suddenly appearing, is rainwater collecting in the spark plug wells. That will cause all sorts of havoc.
And more details like year and engine, please. My mindreading skills just aren't what they used to be. I see a misfire logged for cylinder #7, so I'm assuming (Danger! Danger!) you've got the V8. If you've got that fault on a V6, something is really wrong.
What's the best way to diagnose a slipped timing chain on these engines?
Hoping the OP sticks around so we can help. My Spidey senses are saying otherwise, as often happens...
As I said in my post, it's only a guess; but, based on my own experience with my V8 (Bought myself a new toy thread) I got the cam code just by having the exhaust cams 1 tooth out of alignment.
I know you can get away with the cams skipping 1 tooth and not have the valves contact the pistons, and the car will still run, but any more than that you're in trouble.
As the OP said, it was running the previous day with no issues. Tried to start in the morning and SOUNDS HORRIBLE, then all these codes.
With the cams slipped more than 2 teeth out, the sensors will detect everything not sending signals at the right time. Plus with a slipped chain, it may well start but will sound like a devil juice diesel motor.
I would at least check the timing positions first before doing anything else; flywheel timing plug, valve covers off to check positions of cams, inspect upper tensioners and chains etc.
Unless of course when I opened the bonnet I could see anything that said different, like a dodgey plug connector on the upper engine harness maybe.
All cylinders Misfiring
