Minato's Yin-Kurama Mode and Shisui's half-body Susanoo doesn't matter against Asura's chakra avatar and Indra's Complete Body Susanoo: while Asura and Indra are fighting, Minato and Shisui gets squashed.

As for Tobirama and Neji... Like Thekillman said, collateral damage along with Minato and Shisui.

And before anyone tries to say, "But Ultimate Ninja Storm 4 Shisui!", it ain't canon. Technically, Shisui having Susanoo at all wasn't confirmed in the manga, but at very least it's not impossible for him to awake it.
