How to add physics to round objects?

Question

Unity

Let's say I have such an object, Circle Collider 2D with SpriteRenderer

As its physics of a round object, for example, so that if they all fall from above, then they add up in a physical way, such

that their borders are round and they touch other borders and do not fly as if they were physically falling down, and if they stumbled, they physically bounced off and flew down ...

Tell me either how to do this or what exactly to look for on the net?
