Helicopters carry from 1 - 90 passengers
There are many different helicopters, the biggest can carry over 100 passengers. Most commercial helicopters seat about 16-20 passengers
There are so many small and medium helicopters there is no such thing as "regular" . Most helicopters other than large military ones, carry between 4 and 8 passengers.
The largest helicopters don't carry people. The largest passenger carriers I can think of are the Russian Mi-26, which can carry about 90 passengers.
Most civilian utility helicopters carry 6 -12 passengers. Larger industrial and military helicopters carry more. The CH-47 Chinook, as shown above can carry 55 passengers. The largest helicopter Russia's Mil -26 can carry over 100 passengers, but seldom does as they are usually used in logging and heavy military cargo lifting.
Over here you can carry as many passengers as the car is designed to carry.
