After divers brought out four of the boys Monday morning (NZT), authorities indicated the rescue operation would continue for a third day.
Each of the rescued boys has been guided through the dark winding cave by a pair of divers.
Thailand has been riveted by the dramatic rescue mission to save the "Wild Boars" team after they first became trapped in Tham Luang more than two weeks ago by rising flood waters. Another two more boys left the cave complex a short time later followed by the fourth boy.
The rescue mission is expected to resume Tuesday morning local time to bring out the remainder of the team.
So far eight boys aged between 12 and 16 have been led out of the cave system by a team of expert divers over two days.
Since the operation started, the area outside the cave's entrance has filled with media, volunteers and onlookers.
Dr Richard Harris, 53, an anaesthetist from Adelaide, undertook the unsafe dive to reach the boys and their coach last Saturday, reported The Sydney Morning Herald.
The boys also have a TV in their hospital room, but can't watch it yet for the sake of their mental health.
"For the second lot of patients arriving last night, whose ages range from 12 to 14, they arrived with very low body temperature, and one of them had a low heart rate", he said.
Rescuers say they will extract the rest of the squad and their coach on Tuesday as heavy rains return.
Monday's rescue effort took about nine hours, two fewer than the day before, in a sign of growing confidence and expertise.
Narongsak said, "We expect that if there is no unusual condition. the 4 boys, 1 coach, the doctor, and 3 SEALs who have been with the boys since first day will come out today".
He said, "the kids are footballers so they have high immune systems".
Three ambulances along with cars, hummers and soldiers have been seen entering the cave site where rescuers have been carrying out a high-stakes operation to bring out trapped members of a youth soccer team.
The Guardian reports the head of the joint command centre coordinating the operation, Narongsak Osatanakorn, telling reporters today: "Although [Musk's] technology is good and sophisticated it's not practical for this mission".
"They are diving in something considered (an) extremely hazardous environment in zero visibility, the only light that is in there is the torch light we bring our self".
The hoped-for final chapter in an ordeal that has gripped the world came after elite foreign divers and Thai Navy SEALs escorted eight members of the "Wild Boars" football team out of the Tham Luang cave in northern Thailand on Sunday and Monday.
People across Thailand cheered the rescue operation, including at the Mae Sai Prasitsart school where six of the trapped boys are students.
The rescue missions take almost half a day to complete.
Officials scotched any chance of using tech billionaire Elon Musk's mini-sub made of rocket parts to rescue the remaining boys.
