    Lights are not working too laggy on low end mobile devices. I have decreased shadow quality disabled all. but it looks awful. How can I make this look good like this

    Your entire scene setup would need to be reworked, if you would like to achieve similar results to the Snooker Stars that you are using as a reference. Here are some pointers:
    • Make sure you switch to Linear color space for a more accurate material representation
    • Find a nice HDRI that so that your cue balls could pick up convincing reflections. Don't forget to place a reflection probe that encompasses your pool table
    • Disable all realtime shadows in your scene, and make use of baked lights
    • In order to emulate shadows under the cue balls, you can try using a a projector component with a fake soft shadow - https://docs.unity3d.com/Manual/class-Projector.html
    • Make sure that realtime global illumination is disabled, and rely on baked lightmaps instead
    I would recommend that you would start from the very basics and work your way up.
