Kohonamaru solos Zabuza low difficulty. He's stronger than everyone in the village barring Naruto, Sasuke, and Lee if he mastered Gate of Death by now.
How's he dealing with the OP tech Silent Killing & dealing with the mist though? If you can't see, you can't fight- period. Even in the war, Kamui Bloodlusted Kakashi, Might Guy, Lee, Sakura amongst others couldn't fight back and the fight came to a complete stop as they were forced into blind submissive defense yknow? They were lucky they had someone with prior experience to solve the jutsu.
Sarada is the only one with sensing abilities and I doubt there's going to be a chance to alert her sensei every time he's in danger and for him to react in the speed these guys assassinate.
Konohamaru, if we're treating him like a Hiruzen/Sage Naruto/Asuma mash-up would wreck an all-out open battle against much much stronger opponents but it's not that kinda fight. That said, their power as a team far outweighs these two.
