>Keihan or Keifuku line or Eidan Eizan?
These are not JR line and not covered by JR Pass. But you can use the Pass for JR lines in Kyoto.
Addition:
>Is JR line inside kyoto useful for sightseeing ? Or shall I purchase 2 day Kyoto travellers card?
There are not so many JR lines in Kyoyo. So you have to buy the 2 day card or ticket for each ride.
