It doesn't seem like Danzo could see through any of his Sharingans implanted in the arm, making them suitable only for Izanagi and genjutsu recognition which they both displayed. But if he couldn't see through them, it means they were useless in terms of Sharingan basic abilities, i.e. no movement prediction, no insight power etc. Thereby, the only Sharingan Danzo was able to use by the ortodox means was Shisui's eye.
