Can I freeze buttermilk and use it after it as been frozen?

Never to use expire products as possible specially in intake products. better to dispose it properly.

yes

No reason why you can't.

Yes it can but why would you do that? once it is defrosted it will loose it's flavor and spoil in a short time

yes a freezer is capable of doing this and so much more

Butter milk is 'usually' what remains when full milk (3%bf) or cream (10%bf) has been agitated to release its butter fat (bf). But if you are trying to 'substitute' a small amount in a recipe, say for muffins or coffee cake -- then adding a tsp. or so of lemon or vinegar to whole milk will do -- or diluting some real yogurt with water or milk, to the quantity the recipe requires.
