Face ID
My Iphone use the face id of my brother, he go overseas and not logout the face id in the phone.
I have password and apple ID but can't log out the face id. How I can log the Face ID out without the old Face ID?

To the best of my knowledge, you can't. That's the entire point of that sort of security. If it was easy to bypass, it wouldn't be any sort of security. You can try resetting the iPhone back to factory settings:
How to factory reset your iPhone, iPad, or iPod touch - Apple Support
but if he also set Activation Lock, there will be no way you can use that iPhone unless your brother can remove Activation Lock through his iCloud account.
