Kind of, but not really. The cloak boosts their power, but their base chakra reserves don't increase, they get a temporary boost, like an influx of external chakra. Hagoromo gave Sasuke half his chakra, so now Sasuke's base reserves are much larger than before.
Lol, no. That was most likely a representation of Hagoromo with the Juubi, hence him having his Gudo Dama...unless he somehow had them before.
Either way, Hagoromo without the Juubi>>>>>>>>Hashirama in chakra reserves considering he made the Moon using Chibaku Tensei, a justu that's strength is proportionate to the amount of chakra you put into it.
Lol, not only do you have no proof for the bold, where did those numbers even come from? None of the Bijuu's chakra even begin to come close to the Juubi's. Naruto has known Kurama's power for a long time now, but when he sensed the Juubi, he said it was immeasurable. Kurama doesn't come close, neither does Hashirama.
Lol, what?
1. Hashirama has never fought for more than a day at the most. So that's fanfic.
2. Madara's level? Are we serious with this stuff? Sasuke gets half of Hagoromo's chakra, the guy who made the Moon with Chibaku Tensei, yet his chakra is on Madara's level of all people?
Smh.
