Is "Additional information from an authoritative answer" a higher
trustworthiness sub-rank than "Additional information from
non-authoritative answers"? Or are there no sub-ranks and they have the
same trustworthiness?

RFC 2181        Clarifications to the DNS Specification        July 1997

5.4.1. Ranking data

   [...]

   The accuracy of data available is assumed from its source.
   Trustworthiness shall be, in order from most to least:

     + [...]
     + [...]
     + [...]
     + [...]
     + [...]
     + [...]
     + Additional information from an authoritative answer,
       Data from the authority section of a non-authoritative answer,
       Additional information from non-authoritative answers.
