Neteyam is the eldest child of Jake and Sully, and grew up with Spider. So, if Na'vi gestates for a similar period to humans, Neteyam is around fourteen years old. Lo'ak is the younger brother of Neteyam, but the two seem to be approximately the same age. That makes Lo'ak around thirteen to fourteen years old.
Neteyam is the Avatar Jake and Neytiri characters' eldest son, meaning he's probably around fourteen years old. While Lo'ak is technically Neteyam's younger brother, the two are nearly indistinguishable in age and act very similar, meaning Lo'ak is probably either 13 or 14 years old.
Lo'ak and Kiri are 14 years old in Avatar: The Way of Water, while Tuk is only eight. So, it sounds as if the fourth movie will open with Lo'ak, Tuk, and Kiri at the same ages they are in the third installment, and then they will age six years following the time jump.
Avatar 2 - Jake Sully ENTIRE Family Tree Explained
How old are Loak and Neteyam?
Neteyam is the eldest child of Jake and Sully, and grew up with Spider. So, if Na'vi gestates for a similar period to humans, Neteyam is around fourteen years old. Lo'ak is the younger brother of Neteyam, but the two seem to be approximately the same age. That makes Lo'ak around thirteen to fourteen years old.
A deleted scene from the end of Avatar (2009) revealed that Neytiri was pregnant, so Neteyam was born shortly after the events of the original movie. In accordance with the sequel's timeline, Jake and Neytiri's son Neteyam is nearly 15 years old in Avatar: The Way of Water.
For one, even if Neytiri is 18 in human years, she's the Na'vi equivalent of a human in their early-to-mid-twenties. This is proven in three different ways: James Cameron has stated that Jake's avatar body is around 17 human years old.
Lo'ak is the fourteen-year-old son of Jake Sully and Neytiri, and one of the main protagonist of “Avatar: The Way of Water”. His rebellious spirit is portrayed by his outfits, garments and hair.
Her father is not a father, her father is another mother, Eywa, the Great Mother, the sentient life force of Pandora itself that exists in all things there, but is rarely understood. So essentially yes, Kiri was born from Eywa just like Anakin Skywalker was allegedly conceived by the Force itself and its midichlorians.
Lo'ak te Suli Tsyeyk'itan is the fourteen-year-old son of Jake Sully and Neytiri, the younger brother of Neteyam, the older brother of his only biological youngest sister, Tuktirey, and the younger adoptive brother of Kiri.
He tries to understand her thoughts and feelings and shows affection by calling her "baby girl". When Kiri falls into a coma, Jake calls Norm and Max to come all the way to the oceans to help her.
Kiri is the inquisitive and intelligent adopted daughter of Jake Sully and Neytiri. Not long after Grace Augustine's death, her dormant avatar was discovered to be pregnant, and Jake and Neytiri adopted the child when she was born.
Neteyam seems to be at least a few days older than Kiri, since we see Neytiri holding him while Grace's avatar is still pregnant (but yes they are definitely very close in age).
Natiri, on the other hand, was 18 in human years when Jake met her. And since 15 years have passed since the original film, that means Jake is mentally 37 and Natiri is 33.
The Na'vi are monogamous creatures who mate (Na'vi name: muntxa si meaning "mate with, marry") for life. The mechanics of their reproduction are similar to that of humans and other Terran mammals. However, their unique physiology creates an experience fundamentally different from that of humans.
Since Lo'ak is old enough to be a warrior in the Omaticaya clan, it's likely that he is 13 to 14 years old. Lo'ak and Neteyam are pretty similar in age, so Lo'ak is probably around 14 years old.
Even though he wasn't close with Spider as his brother, Neteyam mostly did it out of obligation to Lo'ak. This unfortunately led to Neteyam's death, as he was killed by an RDA soldier during the Battle of the Three Brothers, trying to help Lo'ak save Spider.
Neteyam was only 15 years old when he died during the climax of Avatar 2. He and his younger, more reckless brother Lo'ak were determined to save their symbolic brother Spider, the biological son of the antagonist Miles Quaritch.
The short and easy answer is, No. But, it's important to note that the Avatar franchise has brought dead characters back in the past. The Way of Water brought Quaritch back as a recombinant.
