Prosecutors have said Colston-Hayter, of no fixed abode, was one of the ringleaders in a gang which stole card details belonging to thousands of people and raided Barclays and Santander branches using special devices.
Co-conspirators Darius Bolder, 34, of Chelsea, south-west London, and Michael Harper, 26, of Gospel Oak, north London, pleaded guilty to using a credit card in the name of Mr Alfieri to buy three Rolex watches at Selfridges.
Bolder also admitted stealing credit balances from Barclays on or before April 5 last year.
Another two men – Segun Ogunfidodo, 26, and Leroy Odunusi, 24, both of White City, west London – pleaded guilty to conspiring to commit fraud using credit cards.
Asad Qureshi, 35, of South Kensington, and Dean Outram, 34, of Kensal Rise, north-west London, have previously admitted offences linked to money stolen or laundered from Santander Bank, the court heard.
Alleged ringleader, Lanre Mullins Abudu, 25, of Putney, south-west London, denies charges of fraud, theft, and possession of articles for use in fraud and will stand trial along with four other men.
He and Akash Vaghela, 27, of Hounslow, west London, deny conspiring to steal credit balances from Santander Bank using a keyboard video monitoring (KVM) device on September 12.
Duane Jean-Jaques, 24, of north-west London, denies conspiring to steal from Barclays and a charge of concealing criminal property.
Steven Hannah, 42, of Marylebone, north-west London, and James Lewis Murphy, 34, of Chelsea, south-west London also deny conspiracy to commit fraud using credit cards on before September 19 last year.
All five men will stand trial at Southwark Crown Court on February 17.
Judge Alistair McCreath said all of the defendants who pleaded guilty will be sentenced following the trial.
Colston-Hayter and Mullins Abudu were remanded in custody, while the other defendants were released on bail.
