JR Pass for this itinerary?

Hi,
we are a group of 14 including kids travelling from 12th May 2020 to 26th May 2020. we would be landing in Osaka. we would be going to Kyoto the same day and start the tour fro there.
In short Kyoto (3 Nights), Osaka (3 Nights), Hakone (1 night), Disneyland (2 nights) last Tokyo (5 nights). we are confused about the JR pass, would be helpful for this itinerary?

Please help in making the decision. we were thinking of buying the 7 day pass since the last 7 days we would be in disneyland and tokyo.

Thanks in advance,
Gautam
