I assumed the chakra exhausted because Minato and Kushina's small portion of chakra was lost, Obito's chakra was lost, so how are we to assume tailed beast chakra regenerates, chakra works that way, isn't it?

Minato and Kushina only sealed a small portion of their chakra into the seal. They used it all up while talking to Naruto. This makes your point invalid as the chakra was completely lost.

As far as Naruto goes, he had the chakra of all Nine Tailed Beasts within him, and from what we know in the final chapters, he still has the chakra as it was determined that Naruto should be the meeting ground of the Tailed Beasts. He hasn't used it all up.

From what we've seen in the manga, even when you split a Tailed Beast, they are able to gather more chakra inside Naruto. Kurama was split for nearly the entire series and yet he gathered chakra for Naruto time and time again. The other Tailed Beasts should be able to do the same inside Naruto.

You cannot equate the small amount of chakra that Minato and Kushina, who are humans, to the chakra that the Tailed Beasts gave Naruto. It's illogical. We have every reason to assume that the Tailed Beasts can regenerate their chakra if need be, even when their chakra is split, as demonstrated by Kurama.
