Meanwhile, Fianna Fáil's Barry Cowen and the Fine Gael pairing of Maria Walsh and Nina Carberry will all win seats.
The fifth and final seat looks like going to Independent Ireland's Ciaran Mullooly, who has now regained a lead over Sinn Féin's Michelle Gildernew.
The exclusion of another Fianna Fáil candidate Lisa Chambers has preceded the next count. The final count is expected before midnight.
