Addresses with www

is there any way to make all addresses

If you mean automatically, no.

If you want the main site to be www then you need to change the single site to www before you set up your network. After that map all your domains with the www. included in the mapped domain.

Then you can use a rewrite rule in your .htaccess to redirect the non-www domain to the www. Keep in mind that once you add the rewrite rule mapping a non-www domain will cause an endless rewrite loop.
