@Ali Keleş , If these domains are currently in the state of unverified domains in the Azure AD Portal, then you just need to register these domains in GoDaddy andget them domain verified. You can find more details on getting your domain verified here: https://video2.skills-academy.com/en-us/azure/active-directory/fundamentals/add-custom-domain#add-your-dns-information-to-the-domain-registrar
For your second question, from Azure's end we do not charge anything for moving domains to different GoDaddy accounts.
Hope this helps.
