Assuming everyone is from Part 1 here and at the time frame OP listed. Is Kakashi with Team 7?
If not: It's Naruto w/ Rasengan, Sasuke w/ CS1 and Chidori, Sakura, and Kabuto vs the Sound 5. Kabuto is underrated or at least the Part 1 version, I think these guys can get the upper hand pretty easily. If Naruto is pushed to his limit he'd go KN0 or even worse KN1, I gotta hand it to Naruto for beating these guys pretty easily if he's allowed to go KN1. Unfortunately, Kimimaro's on that team as well, Kabuto would put up a good fight but as shown previously, most of the Sound 4 crapped on Pre-VotE Naruto and Sasuke.
So with that said their best chance is KN1 and Kabuto putting up a good fight, but Kabuto would eventually die in the end and if KN1 does his best he could honestly pull a win because no one on the Sound 5 could kill him. He hadn't shown KN1 up until this point either though, so yeah they'd probably lose.
if Kakashi=yes:
lol team 7
