Watashi wa Joy desu. Yoroshiku onegaishimasu!

I'm taking beginning Japanese, and a project that sensei gave us is to ask questions to Japanese people, or Japanese speaking people who have lived in Japan for some time. The main thing is to be able to communicate in Japanese and learn the culture.
Chotto ii desu ka? I have a few questions I'd like to ask.
1. Nannensei desu ka?
2. Gakkou no namae wa nan desu ka?
3. Dono kurasu ga suki desu ka?
4. Dono kurasu ga kirei desu ka?
5. Nanji ni okimasu ka? (To get ready for school. How do I ask this in one sentence?)
6. Gakkou ni wa dou de ikimasu ka? (Edited, but still not sure)
7. Obento wo mottekimasu ka? Donna tabemono? (Edited)
8. Dare ga obento wo tsukurimasu ka?
What other questions should I ask? Please answer these questions! Onegai! Doumo arigatou gozaimasu~
