Is it worth moving the type declaration to a separate file?

Question

Programming

Hello.
There are 7 type declarations.
All 7 types are used in 2 classes.
The classes themselves are in several .cpp and .h files.
At the moment the type declarations are duplicated for both .h.
Should I move the type declarations to a separate .h and include them in the classes? Are the type declarations currently implemented correctly?
