What you are asking is not how many types because they are all registered nurses, the only differentiation as in types, is Mid-wifery as its a separate discipline.
An RN is the base from which we gain skills in different areas...maybe this is what you're asking. An ICU nurse is required to know skills that are different to that of say an ED nurse. Forgive me if i am not comprehensive but the areas that require additional training are - Mental Health nursing, ICU nursing, ED Nursing, Oncology and Theater nursing. On average they need to do an additional transition year to gain their respective skills and certification.
