Yes, the Third Hokage did take his place after the death of the Fourth Hokage. Following the Fourth Hokage's sacrifice to seal the Nine-Tails inside Naruto Uzumaki, the Third Hokage resumed his position as the leader of the Hidden Leaf Village. He continued to serve as Hokage until his own death during the invasion of Konoha by Orochimaru and his forces. **

The 3rd Hokage was chosen to succeed the 4th Hokage because of his experience, leadership skills, and dedication to the village. He had previously served as Hokage before and was well-respected among the villagers and other ninja. Additionally, the village was in need of a strong and capable leader to guide them through a difficult time after the 4th Hokage's death. Overall, the 3rd Hokage was seen as the best candidate to take on the role of Hokage once again. **

The fifth Hokage, Tsunade, comes into office after the third Hokage, Hiruzen Sarutobi, because she is chosen by the village elders and the Fire Daimyo to take on the role. Tsunade is a highly skilled and respected ninja, known for her medical expertise and combat abilities, making her a suitable candidate for the position. Additionally, her strong ties to the village and her desire to protect it make her a natural choice to lead the village as the fifth Hokage. **

Sarutobi is the 3rd Hokage because he was the leader of the village before the 4th Hokage took over. He served as the Hokage for many years and was highly respected for his leadership and wisdom. When the 4th Hokage sacrificed himself to seal the Nine-Tails inside Naruto, Sarutobi was reinstated as the Hokage to lead the village once again. His experience and dedication to the village made him the natural choice to resume the role of Hokage. **

It is difficult to predict whether Boruto will become Hokage, as the series is still ongoing and his character development is still unfolding. However, as the son of Naruto Uzumaki, who eventually became Hokage, it is possible that Boruto may aspire to follow in his father's footsteps and become the leader of the village. Whether he achieves this goal will depend on his growth as a ninja, the challenges he faces, and the choices he makes throughout the series. **

It is difficult to definitively say which Hokage was stronger as each Hokage had their own unique strengths and abilities. Hashirama Senju, the First Hokage, was known for his immense chakra and Wood Release jutsu. Tobirama Senju, the Second Hokage, was a skilled tactician and inventor of many powerful jutsu. Hiruzen Sarutobi, the Third Hokage, was a master of all five basic nature transformations. Minato Namikaze, the Fourth Hokage, was known for his incredible speed and the invention of the Rasengan. Each Hokage had their own strengths and weaknesses, making it difficult to determine who was the strongest overall. **

It is possible that Kakashi could become Hokage, as he has already served as the Sixth Hokage in the Naruto series. However, it ultimately depends on the direction of the story and the decisions made by the characters and the village leadership. Kakashi has shown strong leadership qualities and a deep understanding of the responsibilities of being Hokage, so it is not out of the realm of possibility for him to take on the role again in the future. **

No, Orochimaru is not a Hokage. He was never officially appointed as the Hokage of the Hidden Leaf Village. Despite his immense power and knowledge, his unethical and villainous actions have prevented him from holding such a prestigious position. Instead, he has been a major antagonist in the Naruto series, constantly seeking power and immortality through unethical means. **
