The other lights come on to help you notice the "CHECK ENGINE" light (although I don't recall flashing...).
CHECK ENGINE is really a misnomer. Generally, the CHECK ENGINE light means that there is a fault with the emissions system and you may be polluting. A loose gas cap can trigger it. Absent something obviously amiss, it is usually pretty benign and will not effect short-term driving.
There's no way we are going to be able to answer your question without the code that generated the CHECK ENGINE light. If you go to any AutoZone or similar auto parts store, they will read the code for free. Report back and we can probably tell you exactly what to do.

When did they come on?
Was your car just in the shop or inspected?

It's just suddenly turn on when I started the engine in the morning. I've researched, do you think I have a Bad ABS Sensor?

it's possible, but you are WAAAAAAAAAAY better off going to Autozone/Oreilly's/Advance Auto Parts and having them read your codes because even if it was an speed sensor, how would you know which of the four to replace?
If you don't feel like going to one of those places, you can buy an inexpensive scanner from amazon
It will give you the code and a generic meaning of it.

Have you filled your tank lately? As JohnnyCake mentioned, a loose gas cap will cause the check engine light to come on.

I’ve had this happen to me twice. Once was because I started my car with the MAF disconnected and second of my air box lines came off. The check engine light came on first then the other lights. I have a OBD II reader and I reset the check engine light but the other lights stayed on. I found a thread on the LS430 forum to get rid of the lights. You have to get a jump wire from an auto parts store and plug that wire into pin 3 and 5 on your ODB port. Turn the car on but don’t start it let the lights flash and they will disappear and boom! Everything was back to normal. I heard someone taking their car to the dealer and it costing them some ridiculous amount of $$$ to get lights to go away. I hope this helps. The wire was like $3 and it saved me a trip to the stealership.

Exactly, what Jonny said. Nobody can possibly give an answer without the dtc codes

As others have suggested, please go to an auto parts store and ask them to read the codes, then post them here.
Once you give us the codes, we can provide suggestions on what to do next.

That is very helpful. It looks like you have some airbag codes in your history. Probably the passenger knee airbag was unplugged when you connected your battery at one point.
You can clear the ones that says SQUIB and History

Read this article https://repairpal.com/check-engine-l...4-or-p0894-326
It says a combination of the first two codes you have (P0751, P2714) equals the last code you have, an ECM that needs to be updated or a bad ECM. An ECM is an Engine Control Module aka a car's computer.
I do not know if that is your problem, but it kind of looks like it maybe. I would use your scanner to clear all the codes and see if they come back. If you don't have access to the scanner anymore, you can disconnect your battery for 2 minutes and then reconnect it.
I noticed the screen says there are 10 codes, but you only showed 7. Are there three more codes?
If it is not a PCM problem, it is possibly a transmission solenoid problem.

Did you do some work on your PCM and that is why your airbag was disconnected?

Nope! Not on the PCM. However, I did a transmission fluid changed 5 months ago. Do you think this issues came up after I did a transmission fluid changed?
I did a water pump, timing belt, brake, and radiator leaked replacement.
