1) Madara is the only person who awakened Hagoromo's chakra by mixing Indra and Ashuras chakra

2) Again everyone has their own unique chakra, Hashirama/Naruto and Madara/Sasuke's chakra isn't 100% Ashura/Indra.

3) No go re-read the chapter. Naruto was dying because he didn't have any tailed beasts and they didn't appear in his mind until almost the end of the conversation. Minato and Kushina are different because Naruto was alive. They met Hagoromo because they were on deaths door. He said he had been traveling through time to see what would become of Ninshuu so he existed separate from the transmigrants. And according to this, he got the Rinnegan from Hagoromo, no Senju cells mentioned http://www.reddit.com/r/Naruto/comments/2mi8cr/translation_completed_uchiha_sasuke_4th_databook/
