According to a report prepared by business restructuring specialists KR8 Advisory, headline act Nelly Furtado's production company is owed £145,775.75.
A company linked to headliner and ex-Eurovision contestant Olly Alexander is listed as being owed £48,000.
The list also includes an entry for first aid charity St John Ambulance - owed £47,330.40 - while the company in charge of event venue Mayfield Depot is said to be owed £330,329.
It also says security firm Practical Event Solutions has not been paid £167,892.
The new information also reveals some of the background to Manchester Pride's decision to enter liquidation last month.
It says directors sought legal advice in early September after ticket sales for its August Bank Holiday weekend event were lower than expected.
The charity unsuccessfully explored "rescue proposals" before announcing it would go into liquidation on 16 October, according to the report.
