Find my Friends device list

My husband always uses Find My Friends to see my location I got a new phone this weekend and he can no longer use Find My Friends to find me. I showed him how to do it through messages, but how do I allow him to see it on Find My Friends. I go on the device list and I see three iPhones associated with my name, but there are no details and no locations listed for any of them. Are they just all my old iPhones and I can delete them all? But why don’t I see my new one? They should at least tell me iPhone 11 Pro iPhone 8 or whatever. Thanks in advance
