Police arrested the group after executing several search warrants between March 25 and April 3.
After a public appeal last month, a 24-year-old Lalor man and 23-year-old Berwick man were charged with affray.
A 21-year-old Bulleen man and two 27-year-old Cairnlea men were also charged with affray and failing to comply with a direction to assist.
Those five men were bailed to appear before Melbourne Magistrates’ Court on June 13.
Police also arrested a 20-year-old Mount Duneed man, an 18-year-old Dandenong North man, and a 26-year-old St Kilda man.
They were released pending summons for affray offences, while a 17-year-old Mount Waverley boy was issued with a caution.
Detectives earlier released images of nine men they wanted to identify in relation to the incident in March.
Two have been identified and were arrested during the series of warrants, but there are still seven men police want to speak with.
