Yes.
7 lights is the maximum.

This isn't a DBPro limitation, it is a limitation of DirectX & your graphics card.

Is there any way to make more (working) lights with DBPro?

via lights culling. Simply put, it's just a way to effectively to turn off the lights where it isn't needed. It is essentially to keep the minimum lights that are on at a time.

I need more than 7 together - I need 10-30 lights! Can I do this with shaders?

I don't know about shaders, but you can simulate lights with lightmaps.

Then no, it can't be done. Lights are 99% of the time faked anyway - light maps, clever textures, shaders, etc. Rarely are they all real hardware lights, video cards just can't do that many yet.

You will have to find another way.

I've asked about shaders... can I use spot, point and directional lights with shaders?

Yep, you can use directional, point, and spot lights in shaders.
But the big question is, how do you want your shader to be? Technically speaking, you are still restricted with 8 hardware lights in shader. What you can do is just fake lighting by some per pixel lighting calculation, which is like adjusting the color value of each pixel manually based on your requirement.

Hmm... I guess this is as clear as a mud.
