When you use the Shinkansen, you don’t need to look for station staff on the platform, and no one is waiting for you. Because you can board the train without the staff. Regarding

2), unfortunately, the Shinkansen has not yet opened from Kanazawa to Kyoto. Currently, it is open only to Tsuruga, which is quite far away. The only way to get from Tsuruga to Kyoto is to use a limited express train or a local train on the conventional line. By the way, it takes about an hour to use the limited express train, and about an hour and 40 minutes to use the local train. Regarding

3), it is as I wrote at the beginning. Regarding 4), I think you can solve it by telling the station staff at the ticket gate. Regarding

5)?, there is no direct train from Fushimi Inari Station to Nara Station, so you either have to make a complicated transfer on the way, or go back to Kyoto Station and take a direct train. Also, depending on your destination in Nara, you have to think about whether to take JR or Kintetsu. And the important tourist spots in Nara are far from both of those Nara stations. If you change trains on the way to Nara, you will use all local trains, so you don’t need to make a reservation. If you are heading from Kyoto Station, it depends on the railway company you use. Advance reservations are required for Kintetsu express trains. Reservations are not required for local trains and JR trains. Suica cards can be used. As mentioned in 4), there are ramps at stations. But unfortunately… for example, the road to Todaiji Temple is very far from JR Nara Station…
