How to use JR Pass

Hi,

I will be arriving to Tokyo Narita Airport on February 15th.
My itinerary is as follows:
2/15: Narita-Osaka
2/16: Osaka-Nara-Osaka
2/17-2/18: Osaka
2/19: Osaka-Kyoto
2/20: Kyoto
2/21: Kyoto-Tokyo
2/22-2/25: Tokyo
2/26: Tokyo-Narita Airport

I am planning to use a 7-Day JR Pass on the first day so I can use it to return to Tokyo from Kyoto.

Assuming I have a JR Pass, I want to know if there are trains a JR Pass can be used (if so, what lines/trains?) for the following trips:
1. Narita Airport-Osaka
2. Osaka-Nara (and back to Osaka)
3. Osaka-Kyoto
4. Kyoto-Tokyo
5. Osaka-Kobe

Thank you very much.
