ANALYSIS OF THE CHARACTERS’ HEIGHTS
Firstly, Captain Jainway is a holographic training advisor based on Captain Kathryn Janeway, and modeled on Janeway’s physical appearance in the early 2370s, complete with uniform according to Fandom Wiki. As a woman, she looks actually taller that can be similar to a supermodel height. So, she is probably 5 feet and 11 inches tall and the second tallest main character.
Secondly, Dal R’ El is a male Human Augment hybrid who lived during the late 24th century according to Memory Alpha Fandom and he is an orphan who quickly becomes Captain (by his own declaration) of the U.S.S. Protostar as mentioned by one of the commenter. As regards to his height, we can say that he is the 4th tallest character among the main characters based on the photo on Space. So, we estimated his height to be 5 inches shorter than Captain Jainway that could be 5 feet and 6 inches tall.
Next, Jankom Pog was a young Tellarite male born during the mid-22nd century, who spent two centuries in cryostasis before being revived in the late 24th century according to Fandom. Moreover, he is the second shortest main character next to Zero. Based on the photo on Space, he is only waist level with Captain Jainway which could be more than half her height. So, we estimated his height to be 3 feet and 4.5 inches tall.
Then, Gwyn was a young female Vau N’Akat who lived during the late 24th century according to Wiki Fandom. On the other hand, as regards to her height, she is shorter than Captain Jainway but taller than Dal R’ El. So, her height is somewhere in between and to become more precise it could be 2 inches shorter than Captain Jainway based on the image on Space. Therefore, she is estimated to be 5 feet and 9 inches tall.
After that, we have Murf, was a Mellanoid slime worm who lived during the late 24th century as stated on Wiki Fandom and he is the shortest among the main characters. Based on the photo on Space, his height is ¾ of Jankom Pog. So, he is 2 feet and 6 inches tall approximately.
Furthermore, we have also Rok-Tahk, was a young Brikar female who lived during the late 24th century as mentioned on Fandom Wiki but she is a giant that makes her the tallest among the main character. She looks like more than half the height of Jankom Pog based on the image on Space. So, she is probably 6 feet and 9 inches tall.
Lastly, we have Zero, was a Medusan robot who lived during the late 24th century based on Memory Alpha Fandom and he is the third shortest main character. However, they have only a little difference in height with Jankom Pog which could probably half an inch taller. So, he is probably 3 feet and 5 inches tall approximately.
