Answers
1. We do not observe a ninth day of Chanuka as a Sefeika D'Yoma because it is a MiD'Rabbonon (Shulchan Aruch Orach Chaim 670).
2. If one causes damage while he is sleeping, he is liable for it (Choshen Mishpat 421:4).
3. Yosef was released from prison on Rosh Hashanah (Gemara Rosh Hashanah 10b).
4. Osnas was carried to Mitzrayim by the Malach, Michoel (Medrash Tanchuma, Vayigash).
5. Dinah, daughter of Yaakov was the mother of Osnas, Yosef's wife (Seder Hadoros).
