convert freecluster.eu into 22web.org ?

So I have one domain (mcm.freecluster.eu) and two subdomains (mcm.22web.org and qadenza.22web.org).

May I have separate databases for each of them?

What is the limit of database size?

Is there a way to delete mcm.freecluster.eu and keep the rest of two? The goal is all my sites to be something.22web.org?

You can have up to 400 databases per account, so yes!

There is no hard limit on database size. But if you have big tables, just make sure the queries you run on them are efficient and don’t torch the database server ;).

Yes, just delete the freecluster.eu subdomain through the control panel.
