Ranks
Academy Student: Academy students (忍者学校性, Akademī-sei) make up the student body of the Ninja Academy, where they are trained and prepared for life as a shinobi. They are not an actual part of the shinobi force, as they are still in the process of mastering the very basics of the ninja lifestyle. However, they can be conscripted as part of the war potential in times of emergency.
E-ranked jutsu
Genin: Genin (下忍; Literally meaning "low ninja", Meaning (Viz) "junior ninja") are the lowest level of ninja and also the ones that display the most difference in power. When they become genin, ninja start to do their bit for their village's economy – being sent on missions that the village gets paid for. They are typically sent either on D-rank missions, which are almost entirely risk-free jobs of manual labor, or, rarely, on C-rank missions, which are a cut above that and begin to verge on real "ninja" work that have a very low possibility of risk to the ninja involved. When Konohagakure was short-handed in upper-level ninja because of the attack by Otogakure and Sunagakure, the village had to occasionally send genin on higher-ranked missions.
Allowed to use C-rank jutsu
Chūnin: Chūnin (中忍; Literally meaning "Middle Ninja", Meaning (Viz) "Journeyman Ninja") are ninja who are qualified to watch over and guide other ninja. Chūnin have reached a level of maturity that primarily consists of leadership skills and tactical prowess. This is because the genin who don't have the skills to become chūnin are weeded out in testing. Some of them, like Iruka Umino and Mizuki, function as Academy teachers and others, like Shikamaru Nara, serve as team leaders in charge of small teams who need to make decisions and utilize the skills of the shinobi under their command to the maximum effect. Chūnin are typically sent on C-rank or B-rank missions.
Allowed to use B-rank jutsu
Tokubetsu Jōnin ( Special jonin): Tokubetsu Jōnin (特別上忍, Tokubetsu Jōnin; English TV "Special Jōnin"; Literally meaning "Special High Ninja"; sometimes known as Tokujō for short) are ninja who, rather than all-around jōnin training, have Jōnin-level ability in a single area or skill, much like warrant officers of real-world militaries. They are elite specialists in their areas and are often assigned as subordinates to regular jōnin when their services are needed.
Allowed to make Custom Jutsu
Jōnin: Jōnin (上忍, Jōnin; Literally meaning "High Ninja", Meaning (Viz) "Elite Ninja") are generally highly-experienced shinobi with great individual skill who serve as military captains. They are often sent on A-Rank missions, and experienced Jōnin may even be sent on S-Class missions (which are considered to be the greatest difficulty). It is not unusual for Jōnin to go on missions alone. Jōnin are generally able to use at least two types of elemental chakra, some genjutsu, and above-average taijutsu skills
Allowed to use A rank jutsu and take up a second element
Anbu:These are highly skilled fighters, unmatched in their ninja skills. you are able to take up a third element
Jonin Commander:The Jōnin Commander (上忍班長, Jōnin Hanchō) is a position in the shinobi system of Konohagakure. As a representative of the regular shinobi forces, they are a member of the council, giving them a say in important matters such as choosing a new Hokage. They are likely the highest-ranking normal shinobi in the village, but still officially a Jōnin themselves
S-class: This ninja can Use S-rank attacks and is unmatched in battle if you see one of these your best chance is to run.
Akatsuki:You can be a member of akatsuki but only granted the rank if you are one of the ring holders. These people are granted the Forbidden ranked jutsu
