Как сказать по Английски: откуда (из какой страны) они? откуда мы? откуда я?

From where?

From what country?

From what country are they?

From where are we?

From where am I?

"From where are you?" he asked me in a hurry.

Can you tell me Jill from what country are they?

Why are you laughing at me? I just want to know from what country are you?

I just do not remember or I just do not know from where am I? _ said the girl with fear.

The stranger approached to us, looked very strange way and asked me whispering. _ From where are you?

I always ask myself the same question. " From where are we?" But I can not understand as we are both from Canada and England.
