Of the 4 that you found, you need to install the one that works for the mobile carrier that the device is used with.

The OEM unlock setting itself has nothing to do with whether TWRP can be flashed. That is just a setting that "allows" you to unlock the bootloader, it doesn't unlock the bootloader, it only puts the device in a state that the bootloader "can" be unlocked if there is a known unlock method.

You can enable OEM unlock as many times as you want, that doesn't mean the bootloader is unlocked. The bootloader has to actually be unlocked using an unlock method.

No, you can't, that has to be changed in system settings, you can't get to the settings because of your screen.

Forget about TWRP. Just flash the same android version that the device had before the issue started and the data won't get wiped. When it comes to flashing Samsung devices with Odin, the only time it wipes your data is when a firmware is flashed that has an upgraded or downgraded bootloader compared to what was already on the device. Flash the same thing the device already had and you won't lose anything.

You need to slow down and pay attention to details about what people post when describing their issue. You are so impatient to answer that you are posting irrelevant and confusing information for their circumstances. They can't boot this device or get to settings. If they attempt to flash TWRP while their bootloader is locked, it could make things worse. Consider the consequences of what you suggest and consider that most people don't know what they are doing and don't know the risks involved or how to check that your suggestions are safe before they do them. They could blindly walk into a bigger problem.

In this situation, the bootloader could very well be locked without them being aware that it's locked.

In the future, I wouldn't suggest that they flash TWRP when the bootloader can't be confirmed. Stop making suggestions if you can't confirm anything.

Making suggestions without being certain of the state of their device will at some point lead to you telling them to do something that makes things worse instead of helping them. I know you really want to help, but jumping the gun and making suggestions can lead to causing more harm than helping.

Make suggestions that you are "certain" will work, don't make suggestions that "could" work under the right conditions. In this case, you can't be certain that flashing TWRP will work so you should not have suggested it, understand? If the bootloader is locked and they flash TWRP but it bricks the device because the bootloader is locked, what then? Bricking the device will be your fault because you suggested something without being certain. You should have asked more questions and gotten more information about the exact state of this device and it's bootloader status, then, if everything is correct, suggesting to flash TWRP would be safe.
