Sure it's okay but you better not, cause you just washed out your teeth not bad they stay cool for rest of the night. If you went to eat something then make sure to brush your teeth again so clean up the teeth from any possible particle. Also the atmosphere of your mouth which if you eat & don't brush your teeth, it will effect your breath's smell till morning specially if things like milk are involved.
No, after brushing your teeth at night, you can't eat again, otherwise, you have to brush your teeth one more time, as it's important to keep teeth clean at night.
Yes, you can. If your stomach is grumbling eat som cheddar cheese which contains enamel-building casein! Read this:

A few bits of sharp cheddar cheese would be fine.
A couple squares of casein-rich dark chocolate before bed would be okay, too, but we're talking little amounts of very low sugared dark chocolate, as chocolate can give . . . nightmares!
You can have small amount of something what you want after brushing your teeth at bed time.
No..brushing before sleep at night is to remove food and dental plaque from the teeth instead of leaving it there through the night, for cavity process can happen very fast when a person is asleep.
Not brushing after you eat, before you sleep on the nighttime, can be likened to having oral excrement...
Whenever you eat/have a meal, our oral microbiota ingest and metabolize the food particle left over, essentially feasting on whatever we consume. Like every other living organism, these oral bacteria excrete as they reap. However, this secondary excrement is highly acidic and can have some unwanted effects on your tooth enamel: Gradually dissolving it and henceforth leading to the occurrence of tooth decay (cavities).
