"Do you have luggage?"
No, and for a few reasons. Firstly, there would really be no need for あなた、since questions are usually assumed to be about the person you're talking to. Secondly, if you're trying to use the verb 持つ、while that verb would work here, that is not quite how you conjugate into the て form. It is always ている or ています、never てあります。
「荷物を持っていますか」 would work, and I believe the same as 「荷物を持っているか」、「荷物を持っているの？」、「荷物を持っている？」、 and I believe「荷物はある？」
