When the city's warning klaxon was sounded, indicating the attack by Sybok's Galactic Army of Light, she came outside the doors of the saloon to see what was happening. (Star Trek V: The Final Frontier)
She was one of the only other significant background aliens not to appear in a screen test with her production name on the clapboard, however, images of her prosthetic and her makeup being applied did appear on the film's Special Edition DVD.
This alien was among the patrons in The Watering Hole when Caithlin Dar arrived at the saloon to assume her new position on Nimbus III. At the time, he was playing pool with another man near the back of the bar.
When the city's warning sirens went off indicating the attack by Sybok's Galactic Army of Light, he stood outside the door of the saloon to see what was happening.
He later joined the so-called army, and stood behind Sybok as the captured Federationstrike team was escorted back to their shuttle.
This character, named "Lost Soul" by the production staff, was played by an unknown actor.
He was described in the script as one of the "two men play futuristic "pool" on a table filled with water."
This alien was among the patrons in The Watering Hole when Caithlin Dar arrived at the saloon to assume her new position on Nimbus III. He was watching the pitchman's advertisement on the display screen near the back of the bar, and watched Dar as she entered the backroom. He also scuffled with a couple other bar patrons as Dar passed by.

The cat dancer was played by stuntwoman Linda Fetters, who was chosen more for her voluptuous figure than her stunt skills.
This character was described in the script as "A SEXY CATWOMAN dances atop the bar, flicking her long striped tail and hissing seductively at her rowdy audience." When she attacks Kirk, the script described, "with a sudden hiss, the Dancing Catwoman leaps over the bar and pounces on his back. As she claws at him, Kirk twirls her around in an "airplane spin" and throws her the length of the room. The Catwoman lands in the "pool" table, sending up waves of water that soak the walls." It is later indicated, as she floats in the water, that she was unconscious.
This character's appearance was designed by Kenny Myers. He spent many weeks testing different patterns of striping, from such exotic animals as zebras and Bengal tigers. The make-up was tested on a willing model, who was required to stand for hours at a time while Myers and his team experimented with the various markings on her. Because the striping was intended to cover the character's entire body, the make-up team had to work around some extremely delicate areas. "My wife used to get jealous," Myers laughed, "until she came along with me a few times to sessions like these. Then she realized that, after a while, it's like working under a car." After a lot of experimentation, Myers eventually settled on the Bengal tiger striping as his guideline.

By the time the cat dancer's scenes went before the camera, Kirk actor and Star Trek V Director William Shatner had, for months, imagined her dancing atop the bar on Nimbus III. The fact Linda Fetters could wear the contact lenses for only brief amounts of time was, however, a major concern. "That meant if I didn't get it right away, we'd have to wait while we got her off the bar, took out the lenses, and then back in them again after she rested [....] I had to think quickly, because I didn't want Linda to suffer needlessly," said Shatner. "She couldn't see at all, and at one point the camera knocked into her. A funny moment occurred when she said, 'I really can't see.' Glenn Wilder then responded, 'In that case, what are you doing Friday night?'" (Captain's Log: William Shatner's Personal Account of the Making of Star Trek V: The Final Frontier, pp. 155-156)
William Shatner was more concerned with how Linda Fetters would handle the scene wherein the cat dancer is thrown into a water pool table by Kirk. To lend a sense of realism to the shot, Fetters was attached to wires at her wrists and feet, so she would be lifted into the air as Kirk threw her forward. Despite Fetters being an experienced stuntwoman, Shatner was somewhat anxious about her safety in performing the scene. "I had been worried she'd get banged around while floating in the air," explained Shatner, "especially because she would be dangling near the ceiling until they could lower her to the ground. As it turns out, not only was she a first-class athlete, but she was a real trooper. She was able to keep her body sideways the whole time so she didn't get hurt. And through the whole ordeal, she didn't complain once. She was a true professional." Fetters' attitude and abilities impressed everyone so much that they burst into applause upon completion of the shot.

It has often been reported that she was jokingly referred to by some backstage source or sources in connection with the film as a "Kzinrrett".  In Larry Niven's Known Space works, "Kzinrret" (plural "Kzinrretti") is a term that refers to Kzinti females. Fetters (now Howard) has stated that she herself was unaware of being called this. 
"We at the Paradise Inn attempt to create the closest thing to paradise in Paradise – City, that is." "We have spared no expense to create the closest thing to heaven." "Recreational opportunities are limitless. Nimbus III is famous for its plentiful local wildlife, and the fishing is terrific! Easy financing through Federation Federal can put you in your own home..." "Beam on down!"
The Pitchman was played by actor Steve Susskind. He was credit under "Aliens" as "Pitchman", and described in the closed captions as "Man on TV".
The text commentary in the film's Special Edition DVD said of this man's presentation: "The video screen in the bar showed a gag commercial of an alien huckster trying to sell land on "beautiful" Nimbus III. Behind him were images of lush, exotic alien landscapes, created with simple matte paintings by Rich Sternbach. The joke was that Nimbus III looked absolutely nothing like the commercial. At one point, there was even thought that the gag commercial might be used as a teaser-trailer for the movie." Later in the film, the text commentary further described him as a "real estate huckster."
