Not a simple question.
Some sequences are international standard sequences blessed by ITU-R or
ITU-T or SMPTE.
Some others are definitely publicly available for test and research use.
Some others are available for use in particular standardization arenas
only.
Some others are in a basically unknown state (at least to me).
I don't know of any cases where anyone has gotten upset over use or
distribution of the usual sequences.
