Shark boy can't absorb sage mode otherwise he turns himself into a stone so he gets not diffed and naruto still having two sage clones.

When it comes to bumtachi Naruto can counter his genjutsu by fighting him with his eyes closed or he can just use shadow clones which nullifies genjutsu.

Naruto also has frog kumite to avoid the dark fire.
Honestly itachi is getting mid diffed
