Yes they are correct.
However, be aware that an older, but still widely used, naming convention exists. Under the older convention, the oxidation state of a cation that has more than one normal common oxidation state is denoted not by a roman numeral but by a suffix on the root of the name. For a cation that has two normal oxidation states in a compound, such as copper, the lower oxidation state would have an -ous ending while the higher one would have the -ic ending. Under this naming convention, Cu2S is called cuprous sulfide. CuS is called cupric sulfide. There's a system of suffixes for anions as well.
The roman numeral convention is more straighforward and should be used, but be aware that you may see other names for the same chemical.
