No, in 2026 (under the updated Lightning Lane Multi Pass system), every individual in your party who wants to use the expedited entrance must have their own pass. The system works on a per-person, per-day basis. If you are a group of four and only one person purchases the pass, only that single person will be allowed to enter the Lightning Lane; the other three will have to wait in the standard standby line. However, only one person needs to be the "organizer" on the My Disney Experience app to manage the bookings for the entire group. This leader can purchase the passes and make selections for everyone simultaneously, provided everyone is linked in the "Family & Friends" list and each has a valid pass. Children under the age of three do not need a pass, as they do not require a park ticket to enter.
