We are new hosts. We have a booking for 4 adults, we have the name and number of the person who booked, should we ask for names of all the adults staying?

Yes, if it is mentioned in your listing.

BTW If they also own an Airbnb account, the booker can add them to the reservation.

Otherwise: there is no obligation for the booker to provide the details of the additional guests, but you can still politely ask....
