Resolution Note:
This scene has too many lights so some are not rendered with shadows. The limits are described here: https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@17.0/manual/urp-universal-renderer.html.
The light count is all the lights inside the camera frustum it does not know which lights are obscured by walls etc.
If you want many lights on mobile then typically lights are baked. If the lights have to be realtime, then you could script the lights to be enabled based on where the camera is.
