The five are among seven Lao nationals who had entered the cave in Xaisomboun province to prospect for gold, but were trapped for more than a week when rising water blocked their exit. Two others remain missing.
Kengkard Bongkawong, a Thai cave diver involved in the mission, said in a Facebook post on Saturday that all four of the trapped people had emerged from the cave.
Video footage from the volunteers showed rescuers bringing four Laotian men out of the cave with flashlights strapped to their heads and with muddy clothes.
They had joyful expressions on their faces, and some were crying with relief.
The five rescued people were found by rescuers on Wednesday, but had remained trapped.
Rescue officials said they would continue searching for the two missing people.
A team of volunteers from neighbouring Thailand joined the rescue efforts last Sunday and further reinforcements, including divers from Finland, France, Indonesia, Malaysia, Japan and Australia, have also joined the rescue operation, the volunteer group posted on Facebook.
The international rescue team included some members who were involved in the 17-day rescue at the flooded mountain cave of Tham Luang in northern Thailand in 2018.
In a video shot on Friday, just about an hour before the evacuation of the first man began, Bongkawong detailed the challenge the rescuers are facing in the operation.
The team has set up a station in a large chamber inside the cave, accessible only by navigating more than 200m of twisting, narrow, flooded passages with jagged walls. From there, divers need to dive through a flooded tunnel about 30m before reaching the trapped men.
"To dive in a cave, there are issues with the temperature, narrow areas, control of movement, and managing the panic of the survivor, which will be difficult, but we have to do it," Bongkawong said.
