4. All of the above plus Anglicans/Episcopalians/Church of England and the Scottish Reformation: The Anglican church broke with the Catholic church before the German Reformation, of course, and was in full flower by the time of Elizabeth, which was more or less contemporaneous with the German Reformation. The reasons for the split were different than those of the Germans. The Scottish Reformation was in the 16th century (John Knox was an important figure), and bore theological resemblance to the Reformed movement (two of the great Calvinist theologies are in the Reformed church and the Presbyterian church).
5. All Christian non-Catholics: This is what many people think of as Protestantism, but it is not correct. The Eastern Orthodox church, for instance, is not Protestant in anyone's definition, but it is also not Catholic. The Coptic church, also Christian, is also not Protestant. And, there are other groups which bear some resemblance to Protestant groups (e.g., the Mormons), but which also cannot be called Protestant.
