In the Letterkenny derby, Letterkenny Rovers led 2-0 early on but Bonagee came back to level things at 2-2 before the home side made it 3-2 just before the break.
Rovers put the issue beyond doubt in the second half with their fourth goal from Paul McVeigh.
Defending champions Cockhill Celtic had a 4-0 away win against Derry City.
Swilly Rovers opened their account with a 4-0 win over a weakened Fanad United.
