Do you have a small tie/necktie?
I hope you have = Ich hoffe du hast
"hast" is old English for the verb "to have". So "hast not" means "does not have".
I assume you mean "du hast mich", this is German, and means "you have me". I don't know how you say you have me in Italian, if that's what you meant.

du hast Geschwister is the translation in German. It is translated from English to German. German is mostly spoken in the European countries.
Wie viele Bücher hast du is the translation in German. It is translated from English to German. German is mostly spoken in the European countries.
Du hast keine Ahnung = You have no idea.
Hast Du Geschwister? means do you have any siblings?

Wann hast du Geburtstag = When is your birthday
You hate me
I have missed you can be translated as:Ich habe Dich vermisstorDu hast mir gefehlt
