I don't remember if Obito summoned Kurama or not. I know he released him. Madara tried using the Summoning Jutsu in the war, but that didn't work because Kurama was sealed.

Tailed Beasts obviously do have cells and what not. They physically exist. Their bodies are made of matter except maybe Matatabi/Shukaku. if not they would look like Karama Mode.

Giving portions of chakra doesn't create a another Tailed Beast. Ir didn't happen with Gyukis tentacle, and Naruto didn't create a new Kurama consciousness for ever shinobi he lent chakra to. The machanic you are suggesting doesn't work. Consciousness=/=regenerability

Sora is a non-canon character, please don't bring up what was never a part of the story Kishimoto presented to us.
