Yes, the 3.03 rinex contains c9 observations.
I will try down converting the rinex file but I understand that it cannot
include S-signal data. But I will just check how the QC output will be for
single frequency for experimental purpose.

Technically, teqc can read any RINEX version prior to and including 2.11,
very old RINEX version 1.
And in down-converting any RINEX 3.xx to 2.11 (using the tools suggested by

RINEX 2.11. (Then again, does your RINEX 3.03 file even have IRNSS C9
With only IRNSS L5 observables in the extended RINEX 2.11, I doubt you are
to get the type of qc analysis you are expecting because the analysis will
