I want to make a blogportal where friends can sign up and create a own blog?
Yes, b2evo can do that.
Is it possible to make the sign up process automated?
Yes but "automated" is a very vague description of what you might be thinking in your head.
Is it possible for user to register a subdomain or url, or will it be the registered username?
Yes users can each use a different subdomain or domain (but those domains need to be registered with a registrar)
Is there possible to make restrictions on number of photos or total storage to use on each user?
There is an upload quota per user in the works, it will be available in a future release.
Is it possible to make a frontpage that shows randomly posts from theusers blog - randomly, based on popularity and so on?
Is there any newsletter plugin that the users can implement on their blog?
There is a built-in newsletter feature which may or may not suit your needs. You'll have to be more precise about what a newsletter means to you. Again a thousand different ways to think about it and they can all be called "newsletter"
