Napa was fined $5000,Wakeham $1750,Waddell and Katoa $1250 each and Schoupp $250,but they face the prospect of further financial penalties from the club.
The players completed their 14-day isolation period on Monday,just in time to be considered for selection.
The Bulldogs have 16 of their top 30 players off contract as Barrett prepares to move on a raft of underperformers. However,one player who will extend his stay at Belmore is Jeremy Marshall-King.
The brother of Benji Marshall has just agreed to a new two-year extension,although the club will look at other hooking options on the open market.
Another player they are interested in is Tevita Pangai Junior,who has been exploring expressions of interest from rival clubs.
