I don't think that all non-villain character worth the category "Protagonist". Only the main, non-villanous character usually categorized as "Protagonist", while the main villanous one is categorized as "Antagonist".

For the rest characters, there is a tertiary role called "Tritagonist", which dedicated for the rest supporting roles (or known as third-ring characters), both for the villanous and non-villanous supporting characters. This role also used for the characters that become "bridge" for the Protagonist and Antagonist solve the problem, though.
