Proper indoor lighting without directional light

Hello, I would like to know how to properly handle indoor lighting without a directional light. My scene has a room( its some kind of shop), in which the player and ai-agents can move around. I can get good results by placing long area lights at the ceiling and baking the light, and placing light probes so the dynamic objects are also affected by the baked light.

The main problem is how can i get real-time shadows for the player and the ai-agents ?

You could position a few point lights roughly where the center of the area lights would be. But i don't know if i can or even should have so many shadow casting lights in one scene. I tried placing 6 or so and i think only 4 of them would actually cast shadows.

I would really appreciate some help. For this project, i've kind of given up on it but i really want to know. Thank you.
