more lights in the background

hello, i would like to ask you for help, what should i focus on. I’m doing animation in a great unity and I haven’t known how far in a few days, because I’m stuck in the light and it’s the only thing that stops me. Please help. I have a problem that I add a light spot to a certain place, that’s fine. set osvwtlebi celevo object. I’ll light it blue. then I want to add light, like lamp lighting. I add one light and it’s ok. I will add the other one more order and if I add 3 lights anywhere else, one of them will turn off and not work. I add more light and stop working more and still limited to a certain number of lights and I don’t know what he gave. sometimes the additional light even turns off the spot I have set as the main one … please help.

You must be more specific.
Lets start with this - Build in or HDRP , Forward or Deffered redndering

I have Asset downloaded, only on comic toon shadows. I’m working and setting up a scene and I need to use a lot of lights. Maybe 30 or more. But I’ll use the main light. Then I’ll add an area or a spot, any light. I’ll add it again. And when I add a third light. Then one of them goes off. It’s in the scene and in the game section when I switch it. I add another light and another one goes off, and that way, out of 6 lights, only 3 or 4 are working. That’s all that’s working. And I don’t know how to do it. I have a main light and I have several 3d model lamps in the background, but when I add those lights there and anywhere else, some always turn off.
