They were among four people who died in the incident on Thursday, which officials said happened after the cable snapped.
The governor of Campania told Sky News the four dead were “two couples of tourists”.
Rescuers said the only survivor, a middle-aged man, was in a critical condition.
Sixteen passengers were helped out of a separate cable car that was stuck mid-air near the foot of the mountain following the incident.
They were freed one-by-one in a difficult operation using harnesses, footage on RAI television and other media showed.
Italy’s alpine rescue, along with firefighters, police and civil protection services responded to the incident.
It occurred just a week after the cable car, popular for its views of Mount Vesuvius and the Bay of Naples, reopened for the season.
