multi domain within office 365
You can simply add additional email aliases to those users. As in, user John has primary SMTP address john@advanfile.com and additional aliases john@advanfile.pl and john@cprofit.net. You can have dozens of those added, with no additional cost, and any message addressed to any of those will be delivered in the same mailbox. Sending is only possible by the Primary SMTP address by default, so you got that issue sorted too.
OK, so if I want to receive e-mails from different domains, I just create aliases - I checked it and it works.
Additional licenses are needed only if I want to send e-mails from different domains - so each SMTP requires one license?
To change primary address, I will have to create alias for that one, and then set it as a primary address. The question - what about my mailbox - will remain intact if I switch domains?

Yes, a licensed mailbox can only send from one primary SMTP address at a time (without any address rewriting at the transport, etc...). So I believe you would need another licensed mailbox to simultaneously send from another domain (another primary SMTP address). You could keep switching the primary address though.
Yes, create an alias with a different domain and set it as the primary. The mailbox will remain intact. It will have an effect on sign-in and any scheduled Skype meetings, etc.. as indicated by the warning when you switch the primary:
Hi Krzystof,
You can also create a shared mailbox if you need to send as from other email address.
