Have you come back yet?
If a person, for example my friend, had a trip somewhere (to visit her parents), and then returned, what would be the most appropriate question? - I have some variants here :
1) Have you come back yet?
2) Have you come back already?
3) Did you get back yet?
4) Did you get back already?
5) Are you already back?
6) ...(somthing else may be ?)
I want to know, which variant sound in a more natural way, and which are not correct?
Also, may be there are some diffirencies in their meanings?
I mean, may be the first variant imply, that I expected her to be back, or to be just in the way,..?
Thank you for your help.
