Mother wants to see you.
Father wants to see you.
Sister wants to see you.
Brother wants to see you.
Uncle wants to see you.
Aunt wants to see you.
--------------------
Are the expressions above all correct?
Do I have to write "Your aunt wants to see you."?
The first two are correct, assuming that your sibling is making these statements.
If they are not spoken by siblings, "your" should come before Mother and Father.
In the last four sentences, we usually say "your brother," "your sister," "your uncle," and "your aunt."
The other way to write the last two sentences would be "Uncle George wants to see you" and "Aunt Mary wants to see you."

Yes, all of the expressions you provided are correct. However, whether or not you need to add the possessive pronoun "your" before "aunt" depends on the context of the sentence.
If you are referring to your own specific aunt, it would be appropriate to include the possessive pronoun and say "Your aunt wants to see you." This makes it clear that you are talking about your own family member.
If you are speaking in a general or generalizing sense, such as when giving examples of family members wanting to see someone, you can omit the possessive pronoun and simply say "Aunt wants to see you." In this case, "aunt" is used as a common noun to represent any aunt, not specifically your own.
Both constructions are grammatically correct, but the choice of whether to include the possessive pronoun depends on the intended meaning and context of your sentence.
