Five other defendants were convicted by a jury on 4 June, while Rauf, Royle and Jobe had previously admitted their roles in the smuggling.
The NCA said Devanyl Graham, 26, from Dewsbury, flew to Dubai 18 times.
Heather Jeffrey, 58, her son Sheldan Noel, 30, and daughter Lamara Noel, 34, all from Bradford, collected cash from organised crime groups and flew it to Dubai, the agency said.
All are due to be sentenced at Bolton Crown Court later this year.
NCA branch commander Jon Hughes said the group had operated “on an industrial scale” and exploited airport systems to move large amounts of criminal cash.
