-Area left of Castle was known as Delta Island, but I would call it just Delta now.
-I think what you have labeled as "Big City" was supposed to be named "New Big City" which is stupid, actually the whole island is stupid.
-Ninji Castle is correct, forest below it is named Ninja Forest I think.
-Bottom left island of the map which Ziplock made is known as "The End of the World" I think. (Rather have him confirm this or just not include it)
-Snow Town was named "Sylphia" in GTA
-Nearornor Town, Neorenor whatever it is not totally sure iss more known by "Onett".
-Kull's Fortress= Kull's Castle

There was also areas hidden from the main overworld
-Silmaria (Old Graal)
-Turk Town (Or Village?)
-Sunken Big City
-Golden Realm/Golden Land, might want to label the gate below Brother's House "Golden Gate"

I forget if the mountain with waterfall was named anything in GTA, but it was around Sardon's Tower before so maybe it's a completely different mountain.
