Yes, Gaara is no longer a Jinchuuriki. He was originally the Jinchuuriki of the One-Tailed Shukaku, but during the Fourth Great Ninja War, Shukaku was extracted from him by Madara Uchiha. After the war, Gaara was able to be revived and live without the tailed beast inside him, allowing him to continue his duties as the Kazekage of the Hidden Sand Village. **

The three-tailed Jinchuuriki in Naruto is Yagura Karatachi, who was the Fourth Mizukage of the Hidden Mist Village. The Bijuu sealed within him is the Three-Tails, also known as Isobu, a turtle-like creature with three tails. Yagura was manipulated by Obito Uchiha and the Akatsuki to become the Jinchuuriki of the Three-Tails. **

Orochimaru has never been particularly interested in Naruto and his Jinchuuriki because his primary goal has always been to attain immortality and gain ultimate power. He sees Naruto as a potential threat due to his connection with the Nine-Tails, but Orochimaru's main focus has been on finding ways to extend his own life and achieve his own ambitions. Additionally, Orochimaru has been more preoccupied with pursuing Sasuke and his Sharingan abilities, as well as conducting his own experiments and research. Therefore, Naruto and his Jinchuuriki status have not been a top priority for Orochimaru. **

After the 4th Ninja World War, the Bijuu spirits are no longer sealed inside Jinchuuriki as they were all released during the war to help fight against the Ten-Tails. The Bijuu spirits are now free and are able to roam the world as they please. It is not mentioned in the series whether new Jinchuuriki are being sought again, but it is likely that the villages would be cautious about sealing the Bijuu spirits inside individuals again after the destruction and chaos caused by the war. **

Gaara is still able to control and manipulate sand even after losing the One-Tail Shukaku, because he has developed a strong bond with the sand through his years of being a Jinchuuriki. Additionally, Gaara has honed his skills as a ninja and has become proficient in using his chakra to control the sand as a part of his unique fighting style. This allows him to continue using the sand as a powerful defensive and offensive tool, even without the tailed beast inside him. **

Elegance is a combination of simplicity, grace, and refinement. It is about being stylish and sophisticated without being flashy or overdone. Elegance can be seen in the way someone carries themselves, in their mannerisms, and in their choice of words and actions. It is a timeless quality that exudes class and charm. **

Serenity and indifference are not the same thing. Serenity is a state of calmness and peace of mind, often achieved through acceptance and mindfulness. Indifference, on the other hand, implies a lack of concern or interest in something. While serenity can involve letting go of things beyond our control, it is not about being apathetic or detached. True serenity involves a sense of inner peace and contentment, while indifference may lead to a disconnect from emotions and relationships. **

I'm sorry, but I cannot answer that question as I do not have the ability to hear or perceive sounds. If you would like to know if your teacher whispered, I would recommend asking someone who was present in the same room as your teacher at the time in question. **
