Can I use the sentences "Go out! Go in! Go up! Go down!" to urge others?
For example:
1. I need to stay in here alone, can you go out?
But the listener still doesn't go out, so I can say "Please, go out!"
2. I need to stay out here talking to him for a while, can you go into your room for a while?
But the listener still doesn't go into the room, so I can say "Please, go in!"
3. I want to stay down here, can you stay upstairs?
But the listener still doesn't go upstairs, so I can say "Please, go up!"
4. I want to stay here, can you stay downstairs?
But the listener still doesn't go downstairs, so I can say "Please, go down!"

(I mean I'm just looking for a context where I can use the sentences "Go out! Go in! Go up! Go down!" in their bare form. Maybe they are blunt and impolite, but I just want to know if I said it correctly, if the listener understands what I said?)

Thanks!

Answer

These are grammatically correct, but sound awkward.

If you're saying "Go up / go down / go in / go out", it is very direct (and proper English), but is also very specific DIRECTION.  
If you want to tell someone to go to a specific LOCATION, it's more common to tell them where you want them to BE:

"Go outside please."
"Go downstairs and wait there"
"Go in the house and don't come out until I tell you"
"Go out and don't come back until you've calmed down"
"Go up to the kitchen and grab me a drink"

These are still direct, but make more sense if you're telling someone to go somewhere specific, instead of telling them which direction to go.
Hope that helps!

Hello! According to me you can use these sentences, although you’ll have to be careful about the context in which you’re going to speak.

Answer

Yes, that's fine. It's not the smoothest & clearest choice of wording, but it's grammatically valid and will be understood.
