He doesn't physically have Obito's eyes. He's using Obito's residual chakra at the moment and once that runs out he'll get his previous eyes back.
He has Obito's chakra so yeah
he is using obitos chakra and it will run out when obito runs out (think of it like being possessed by ashura or indra)
This ^ and it improved a lot during the war. He even was confident of having enough chakra to do this.

Haha increased. He should've died by simply forming an incomplete Susano'o, but its kishi manga
Kakashi has always been > Sasuke in chakra amount.
It's not the fact that he can use it but its that he jumped straight from no susanoo to having perfect susanoo....you know the susanoo only gotten by 2 shinobies both getting after getting EMS also what happened to that hate is the source to increasing your power
