The other two men are then seen taking it in turns to separately sit down and talk to Hanamori.
CCTV footage of the men at the airport around the time of the murder was shown in court Thursday.
Vietnamese suspect Doan Thi Huong and Indonesian defendant Siti Aisyah are the only two people in custody.
The site visit covered various locations in the terminal shown in the videos, such as a restaurant where Siti Aisyah was seen meeting an unidentified man, the toilets where police witnesses said both women had gone to after the attack on Kim Jong Nam, the clinic where the victim sought medical aid and the taxi stands where both suspects were seen after the attack.
Wan Azirul testified earlier that the four male suspects at large were known only by pseudonyms.
Kim Jong Nam, who was living in exile in Macau, had criticized his family's dynastic rule of North Korea and his brother had ordered his execution, according to some South Korean lawmakers.
Defence lawyers have argued the women did not know they were handling poison and thought they were involved in a prank for a reality TV show.
Wan Azirul Nizam Che Wan Aziz had identified the four male suspects shown in CCTV footage as Mr. Chang, Mr. Y, James and Hanamori (alias Grandpa or Uncle) during his earlier testimony before the court on October 12.
After the two women rubbed Kim's face with a liquid later identified as VX nerve agent, video footage showed that Chang and Mr. Y had changed their shirts and ditched their caps and backpacks.
Kuala Lumpur: Malaysia will have to play their Group B 2019 AFC Asian Cup qualifying matches against North Korea in Thailand on Nov 10 and 13. "So perhaps tomorrow we will show another two suspects who are still at-large", he said.
Meanwhile, the witness said Mr Y who was wearing a grey T-shirt, a black cap and carrying a backpack before the incident went to the toilet at 9.13am and came out at 9.23am wearing a black T-shirt.
"He was seen arriving earlier than the rest at the scene, where he was also seen walking together with another suspect by the name of James before being approached by Mr Y".
The trial was cut short after the judge said he wanted to review the videos and will resume on November 6.
Aisyah's lawyer, Gooi Soon Seng, told reporters before the trial that she was recruited in early January by a North Korean man known to her only as James to star in what he said were video prank shows. James video-recorded the encounters on his phone, and paid Aisyah between $100 and $200 for each one, he said.
Siti Aisyah and Doan Thi Huong are on trial for the murder of Kim Jong Nam, the half-brother of North Korea leader Kim Jong Un.
