Don't know exactly how should we cope with domains that we have. We've got three different domains within organization:
Now, we'd like to implement the following scenario:
Domains are registered within office365 and MX and TX records are set, but I do not know how should we proceed. Questions:
Please advise, all comments appreciated.

You can simply add additional email aliases to those users. As in, user John has primary SMTP address email@example.com and additional aliases firstname.lastname@example.org and email@example.com. 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:

There are different workarounds you can use in order to send as additional aliases, including some third-party tools that make the process painless. One of the common method is to create a shared mailbox with said address and grant yourself Send As permissions. You can configure some form of forwarding if you want to keep the messages coming to one and the same mailbox. But in general the method can be challenging to use for some users.

Yes, that could be done. Note the shared mailbox will require a separate license though (unless he can meet all of this needs for this mailbox, with the one shared mailbox).
