Spacey is also accused of sexually assaulting a former production assistant on the Netflix drama, according to CNN.
The new accusations come just days after actor Anthony Rapp revealed that Spacey made sexual advances toward him in 1985 when he was 14-year-old.
All the eight people from the show spoke to CNN on the condition of anonymity. They said Spacey's behaviour was "predatory" and involved non-consensual touching and crude remarks.
The former production assistant on the show said Sapcey assaulted him in the car while they were coming to the sets. The actor, who was driving, inappropriately touched him.

"I was in a state of shock. He was a man in a very powerful position on the show and I was someone very low on the totem pole and on the food chain there," he said, adding the actor again made inappropriate contact in the trailer while he was coming out after keeping his belongings there.
The other people who worked on "House of Cards" confirmed that Spacey routinely harassed and touched crew members.
"He would put his hands on me in weird ways," a crew member said.
The crew members said they never complained about Spacey because they were afraid of losing their jobs.
In the light of new allegations, Netflix, which has already decided to end "House of Cards" after six seasons, said they have sent a representative to the show's set on Monday.
The production on the sixth season also remains suspended as Netflix investigates the matter.
In a statement it said, "Netflix was just made aware of one incident, five years ago, that we were informed was resolved swiftly. On Tuesday, in collaboration with MRC, we suspended production, knowing that Kevin Spacey wasn't scheduled to work until Wednesday.
MRC, in a separate statement, said they have implemented "an anonymous complaint hotline, crisis counselors, and sexual harassment legal advisors for the crew."
"We are deeply troubled to learn about these new allegations that are being made to the press concerning Kevin Spacey's interaction with members of the crew of House of Cards," the MRC statement said.
"As the producer of the show, creating and maintaining a safe working environment for our cast and crew has always been our top priority," the statement read.
