A person's ID card bought three tickets. Can you enter by scanning the buyer's ID card only, or do all accompanying persons need to scan their IDs as well?

One person can use facial recognition only, as the others don’t need to scan their faces, since the purchase was made with your ID card. You might need to scan your face three times.
The child is 12 years and 11 months old, should I buy a child’s ticket or an adult ticket?
This friend who must brush everything, how did you buy three tickets with one ID card? I’m curious.
