I think going with that nomenclature most of those countries (Ukraine, Hungry, etc) would be second world countries. If I remember correctly folks in the US coined those terms during the cold war. The first world countries were the US and allies, second the USSR and allies and third world the unaffiliated countries. Third world has come to be used as a term for impoverished countries as many of the unallied countries at that time were rather poor, but that wasn't the meaning. Somebody should definitely spot check me on this postulate before they accept it as fact.
