Domain redirection?

I bought several similar domains and I want to redirect to one main domain. But without hosting. I read the registrar panel should have such a function. But I don't see such a possibility. Can it be missing? Should this feature be free?

Maybe someone had the same problem? How to resolve this issue?

I think it depends on the specific panel of the domain registrar. It should be and it's free. At least I just checked Pananames registrar panel and this feature is called "domain forwarder". Yes, it's free and doesn't require hosting. You can find something similar.

I even think about changing the registrar.... Because this is very important to me.

Yes, you can transfer domains to another registrar. It's pretty simple.
