The fundamental article of faith is justification by faith alone in Christ alone. If we do not believe that fundamental article, we can not believe any of the fundamentals you have listed.
The Roman, Eastern Orthodox, and many Protestant sects are, indeed, heretical since they deny at least one of your fundamentals, total depravity. But these churches have, at least, a correct understanding of the nature of Christ. So the Lord may be pleased to save some of their members.
On the other hand, the Unitarians, Mormons, JWs, Oneness, etc. have no proper understanding of the nature of Christ. They worship idols like the Muslims, Jews, Hindu, etc. They must be considered infidels not heretics.
