There were 12 original apostles, Paul became the 13th. Barnabas was also referred to as an apostle at least twice in scripture. How many more I don't know.But only an apostle could impart the gifts beyond the two outpourings. You need to align other scriptures with this, then draw conclusions.
Just because the scripture is silent on the giving of the baptism of the holy Spirit doesn't mean it didn't continue.
