1-Danzo and tank any move he wants for a total of ten minutes. He has powerful wind jutsu and can put powerful seals on people just by touching them. A, 3rd Raikage and Bee would be defeated in the end.
2-Minato beats Itachi because of better stamina. Tsukiyomi is no problem because wont look into Itachi's eyes. Sasuke on the other hand has great stamina and Minato cant get past Susanoo.
Danzo beating A, 3rd Raikage and Bee is slim.
-A has the ability to kill Danzo 10 times. A has enough chakra to last long enough, and is able to dodge most if not all o Danzo's attacks.
-3rd, like his son has a lightning armor, but his is stronger in defense. None of Danzo's wind jutsus would faze him, let alone touching him would be nearly impossible.
-Bee, like above has the stamina to fight and kill Danzo 10 times. And with the 8 tails with him, a seal wouldn't do much to him. We saw Sasuke burst out of the seal by exploding his chakra basically. And Bee has stronger and more chakra.
On the other note. I see where you are coming from with Itachi but I do feel like some eye contact would be made sometime in that fight, and also Itachi has other ways of getting people into genjutsu
