Could you please suggest me any suitable pass which is convenient and saving?

Have you done a search of the various passes available to work out if one works for you? This forum is not a travel agency.

This website describes many inter- and intra-city passes. Take a look around. I don't think you'll find one to cover everything, in which case you should also consider an IC card for transport not covered in any pass you might buy.

I can't comment on the pass/es you need (would be easy for you to find yourself - just visit the tourist information pages for each city), but I think your day in Kyoto is way too crowded. You'll be rushing, even if you manage to visit all those places (they're spread all over the city). Consider cutting some.

If you're specifically after cherry blossom, I recommend the Eastern Kyoto full-day itinerary listed on this website. It will take you to several of the places you want to see, as well as a couple more that are famous for their cherry blossoms (e.g. Keage Incline).

Also, Kinkaku-ji is a temple, not a castle.
