Not much of a question but today randomly these lights came up. I was pretty shocked and scared. So I took it to the dealer but all the mechs left so I just left it over night. What could be the problem? I know it's not the gas cap because I always double check it.

Nope, I was really confused of why this happened. I do remember when I tried to turn the car on the engine kind of sputtered and stalled. But besides that I don't see why all those codes popped up. But the toyota guys were really really confused. The guy said that if anything, it might be the vvti itself that is acting up so they'll keep the car for one more day and try to figure out. If it's the vvti then they have to open up the engine and fix it which will take approximately 1-2 days which won't be too bad and it should be under warranty.

171 is a system too lean code. 172 is a rich code.

You likely have some sort of issue with fuel delivery. It could be something in the ECM, fuel pump, or other issue. From the codes it looks like it is running out of fuel on all cylinders causing a misfire for each cylinder.
