The Haku feat wouldn't even matter for the most part, as it can't be powerscaled to anyone else, unless you want to include Sasuke trying to intercept the "lightspeed" movement - in which case, his feat is an outlier same as kid Goku outrunning a light wave from Tien back in part 1 dragon ball.
There was a 10-meter distance between Zaku and Sasuke, so what we're looking at here isn't even a supersonic feat necessarily.
The mach 5 statement doesn't tell us anything lol. It's just naruto yelling out "mach 5". It's a big hyperbole.
The whole Raikiri bit doesn't give Kakashi MHS+ reactions if that's where you're going with here. Especially since we don't know if the rumor is true, the circumstances of Kakashi's lightning cutting even if it was true, and whether we're talking about real lightning or chakra Raiton as demonstrated by the Gian feat.
There was a hundreds of meters to kilometers of distance between Itachi and the thunderclouds Kirin came from. Reacting to natural lightning based on those conditions would barely even constitute a supersonic feat (assuming the average speed of lightning).
What's this about Kisame's bullets?
