Bus Pass Itinerary and cancellation policy

The Willer Express Page is so confusing. I'd made a 5 days pass itinerary, but I don't know what covered by Willer Pass, what covered by JBL Pass, and which route isn't covered by any pass, but I still can find on the page... And how can I figure it out?

1. Osaka to Toyama (22:00 WBT Umeda-Toyama)
2. Nagano to Tokyo (13:00 Nagano-Shinjuku) and Tokyo to Hiroshima (20:00 Shinjuku-Hiroshima)
3. Hiroshima to Kobe (23:10 Hiroshima-Kobe Sannomiya)
4. Kyoto to Tokyo (22:55 Kyoto-Shinjuku)
5. Tokyo-Fuji Five Lakes (6:45 Shibuya-Kawaguchico) and Fuji Five Lakes to Narita Airport (13:15 Kawaguchico-Narita)

My second question connect to corona virus (so boring:)). If I'm right the bus pass is fully refoundable if somebody doesn't use it at all. So theoratically if I buy a pass, book my busrides, but my plane will be cancelled. Can I cancell my bookings first and get a full refound?

Thx the answers!
