Freedombox in a VPS

Since I wouldn’t know how to handle security, I would like to set up FB in a VPS, but the following two things are stopping me (1,2 below):

  1. Can I serve other DN (2,3 top domain names, with subdomains, using Apache virtual hosts, nginx, something else) websites, with static webpages, changes to be uploaded via ssh, or sftp?
  2. How far is the team from having email server ready for FB? This second question can wait, since I could host emails somewhere else. (Recommendations are welcome)
  3. Is there a howto available some where that someone could recommend for this?
