How many white walkers are there? I know there are tons of wights and can make more easily. For white walkers, only the ones made by children of the forest (not sure how many they made) and Craster's babies turned by the Night King. I feel like there's less than 10?

I don't remember if Night King or white walkers talked or just sign language. Understand wights are basically just zombies who serve the Night King.

Would love an episode like a day in the life of a white walker lol like do they sleep, eat, get bored etc or just keep on walking.
