How can i remove that noises?

I have a little problem with the lightning/ shaders or what causes the problem im looking to fix
it is something with the rays of the lightning i think or false shading

Just use denoising.You can find it here:

More samples, fewer light bonces, clamping luminosity, denoising, disabling caustics can all reduce noise in renders.

This doesnt help

We need to see your render settings, too. Maybe better to upload a blend file.
