One possible mentor could be Zabuza. Although he was an enemy at first, in a fanfiction scenario, he could have survived and seen potential in Naruto. Zabuza was a master of assassination techniques, and he could pass on his skills, like silent killing and the use of the Executioner's Blade in a more covert way. Also, Orochimaru might be considered in a very dark fanfiction. He has vast knowledge of jutsu and poisons that could be used in assassinations, but of course, this would be a very dangerous path for Naruto to take.

Her strength in close - combat and knowledge of physical combat could make her a great martial arts mentor for Naruto.
Jiraiya could be one of his mentors. He's already Naruto's teacher in many ways and has a vast knowledge of different ninjutsu, so he would be a great choice to teach Naruto about elemental ninjutsu.

She has great control over her chakra and could teach Naruto how to use his chakra more effectively for elemental ninjutsu.
Jiraiya could be one. Although he is known more for his fire and earth - based jutsu, he has vast knowledge and could guide Naruto in using water affinity in unique ways. Another could be Kisame. He is a master of water jutsu. His skills with water manipulation are top - notch, and he could teach Naruto some really powerful and advanced water techniques.
