Sasuke vs. Gaara -> Sasuke (as pointed out, Gaara needed time to recover)
Shino vs. Kankuro -> Shino (forfeit)
Temari vs. Shikamaru -> Temari (forfeit)
From there it's all conjecture.
Naruto vs. Sasuke -> Sasuke wouldn't be able to use his Chidori without killing Naruto, and he's just used his speed boost, so he's low on stamina. On the grounds of useful techniques (Kagebunshin > Konoha flame), stamina, and willpower, winner: Naruto.
Temari vs. Shino -> Shino would have all the upper hand of knowledge. He's gotten to see Temari in action twice, one of which was a drawn out fight. Temari has only seen him once, in which he essentially stood there. While Temari may be good at thinking on her feet, Shino seems to plan the entire battle out before the first punch is thrown. Winner: Shino.
Shino vs. Naruto -> Honestly, I think this would be one of the greatest fights in the series. On the one hand, Naruto's biggest advantage going into most fights is that his opponent invariably underestimates him. Shino, however, goes all out against anyone. The big challenge would be to see whether Shino has enough bugs to eat all of Naruto and Kyubi-Naruto's chakra. That, and as pointed out, Naruto refuses to stay down. And, he's the main character. Winner: Naruto.
Regardless, though, he'd still be a genin. His willingness to take it to the last breath doesn't exhibit good leadership qualities, since they'd have to worry if he'd sacrifice a team with the same mindset. =P
