Limited number of people shown in photo shuffle for lock screen

Hey KernIM23,

We'd recommend reviewing the information in this article as it provides your options for adjusting how people appear in Photos: Find and identify people in Photos on iPhone - Apple Support

"Feature a person in your People album less frequently

You can make photos of certain people less likely to appear in your memories and featured photos, and in the Photos widget.

1. Open the People album, then tap the face of the person you want to see less often.
2. Tap , then tap Feature [name] Less.
3. Choose Feature This Person Less or Never Feature This Person, then tap Confirm.

See Manage memories and featured photos in Photos on iPhone to further customize the photos that appear in your memories and featured photos, and in the Photos widget.

Remove a person from your People album

1. Tap the People album, then tap the face of the person you want to remove.
2. Tap , then tap Remove [name] from People."

Thanks!
