The six released "fully co-operated with officers working on the investigation", West Midlands Police said.
Assistant Chief Constable Marcus Beale, who leads the West Midlands Counter Terrorism Unit, said they were very appreciative of their co-operation and support.
"As a result of their co-operation and our enquiries, we are completely satisfied that they are not connected in any way to the terrorist attack in Westminster on Wednesday," he said.
In the attack, British-born Khalid Masood drove a car into people on Westminster Bridge near the British parliament, before stabbing police Constable Keith Palmer.
He was then shot by armed police as he tried to stab another officer.
The attack resulted in five deaths, including Constable Palmer and Masood, and more than 50 injuries.
The other victims were 43-year-old Londoner Aysha Frade, 54-year-old US tourist Kurt Cochran, and 75-year-old Leslie Rhodes who died on Thursday night.
