Minato, despite being a Kage, an adult and having respectable reserves on his own, said he could not be Jinchuriki of kurama. However, our baby Naruto could take in half.

Clans like Kimimaro's, the Uzumaki etc clearly show that Ashura's descendants spread his abilities among a few clans. So no, it's not that the Senju can use all Tailed Beast powers.

When put under Edo Tensei Madara had his original EMS. Kabuto's modifications allowed him to once more awaken Rinnegan. However, when put under Rinne Tensei these eyes crumble.

This suggests that the Rinnegan produces it's own Six Paths chakra (and is the source of that chakra for Madara).
