Naruto would be in Nine Tails Chakra Mode not n Sage mode. Even if the explosions hit him I don't think anything would happn.Naruto will be able to evade those tiny particles BECAUSE IN SAGE MODE ,HE CAN SENSE CHAKRA AROUND HIM. THOSE C4 PARTICLES DEDIARA PRODUCED ALL HAVE CHAKRA SO NARUTO EVADES THEM...
SASUKE KILLS RAIKAGE AND JIRAYA WITH AMETERATSU OR SUSANOO..AND NARUTO, WELL, HE CAN OWN THEM..EASILY
