You don't read the article well, it seems. First, HCoV is a virus that affects humans, and it does NOT mean it originates from humans. The H just stands for that the virus also can infect humans. Consequently, these current SARS-2 strains are also HCoVs. SARS, SARS2 and MERS have their origin in other species (bats are a suspected source), and are considered HCoVs as humans can host these viruses (as can other species like cats, dogs and so on).
There are 7 HCoVs known/identified, see the article I linked to above. HCoV-229E, HCoV-OC43, HCoV-NL63, HCoV-HKU1 (known as common cold viruses), SARS, MERS and SARS-2. The article you link to says:
"We present findings describing the epidemiology of non-severe acute respiratory syndrome human coronavirus-associated influenza-like illness from a population-based active follow-up study in four different regions of Peru. In 2010, the prevalence of infections by human coronaviruses 229E, OC43, NL63, or HKU1 was 6.4% in participants with influenza-like illness who tested negative for influenza viruses."
So, it says that a study that looks at certain parts of the population of Peru where people are complaining/showing flu-like symptoms, 6.4% show not to have the flu (infections by influenza) but rather have infections of common cold viruses.
