How do you say are at home already in Russian?

There are a few ways to say "are at home already" in Russian, depending on the context and formality:

Formal:

* Уже дома? (Uzhe doma?) - This is the most direct translation and means "Are you already at home?"

* Вы уже дома? (Vy uzhe doma?) - This is a more polite version using "вы" (formal "you") instead of "ты" (informal "you").

Informal:

* Ты уже дома? (Ty uzhe doma?) - This is the most casual way to ask.

* Дома уже? (Doma uzhe?) - This is a very colloquial way to say it, literally meaning "At home already?"

Note: You can also add the verb "быть" (to be) to the end of these phrases for emphasis:

* Уже дома есть? (Uzhe doma est?) - "Are you already at home?" (Literally "Are you already at home present?")

The best option for you will depend on your relationship with the person you are speaking to and the tone you want to convey.
