@Ariria I don't know what titles that guy has, but in feudalism it is entirely possible to possess multiple titles. If you were in charge of a tract of land (which most importantly gave you tax income) it was denoted with a title and you were considered a noble. Multiple claims meant multiple titles. Higher posts in the feudal hierarchy tended to have vassals, lower-ranked nobility that owed you fealty. At the top of this pyramid sat a sovereign monarch who was beholden to no-one, owned certain tracts of land directly and used titles pertaining to those, and practically controlled the rest of the state by owing fealty of the lords beneath.
Well that's the idea of the feudal contract anyway, there were different feudal arrangements in various monarchies of Europe and real world muddied the waters a lot. For example consider the Duke of Normandy who was subject to the king of France but also through conquest the king of England. (Not to be confused with the English claim to the throne of France, which was traced through marriage and came about due to death of all direct male descendants.)
