Can I use JR Pass on my route?

Hello there,

Im going to Japan in January 23rd, 2023 and I have my trip booked as follows

January 28th - Tokyo to Kanazawa
January 30th - Kanazawa to Hiroshima
January 31st - Hiroshima to Miyajima
February 1st - Miyajima to Osaka
February 3rd - Osaka to Kyoto
February 6th - Kyoto to Nikko
February 8th - Nikko to Tokyo

Doubts:
Am I able to use Jr pass in all the routes?
I see Hyperdia is not working, which other site can I use to better plan my trip?
