We don't really have any information except that the Vale/North declared for King Jon... Stark? The Crownlands, Riverlands, Westerlands, Stormlands are under Lannister control. Cersei says three areas but the Crownlands were never really their own thing. Dany has Dragonstone, Dorne, and The Reach. Iron Islands on off by themselves. Beyond the Wall is decidedly controlled by the White Walkers. Of course, this is all in flux. The Others are about to kick some human butt, the Riverlands are in flux to say the least, the Stormlands are MIA, and the Iron Islands are courting Cersei.
