Can I have a friend activate an apple watch for my daughter under her apple id?

Hi there PrimmReeper,

You can have someone else set up the Apple Watch, but there are some parameters that must be met:

You can set up and manage Apple Watch for someone who doesn’t have their own iPhone—your school-aged child or parent, for example. To do so, you must be the family organizer or parent/guardian in your Family Sharing group.

The iPhone you use to initially pair and set up the Apple Watch must be within normal Bluetooth range (about 33 feet or 10 meters) of the Apple Watch to manage settings and update the software. The person you set up Apple Watch for must be part of your Family Sharing group and have a cellular-capable Apple Watch SE or Apple Watch Series 4 or later. (Your family member’s watch doesn’t have to use the same cellular carrier as the iPhone you manage it with.) See the iPhone User Guide for information about setting up Family Sharing.

Take care.
