– Multiple blogs
Yes and no. See: http://codex.wordpress.org/Installing_Multiple_Blogs
I recommend WordPress MU.
– Multiple administrators
Yes and no. WordPress does not support multiple admin users, but you can have as many level 9 users as you want, and they are almost as powerful as the admin user. See: http://codex.wordpress.org/User_Levels
– Comments
Yes, of course WordPress supports comments. It wouldn’t be a blogging platform without comment support.
– RSS output
Yes, of course WordPress supports RSS output. It wouldn’t be a blogging platform without RSS output.
– Categorization (and sub-categorization)
Yes, of course WordPress supports categorization (and sub-categorization). It wouldn’t be a blogging platform without Categorization (and sub-categorization).
– Image/file upload
Yes, of course WordPress supports Image/file upload. It wouldn’t be a blogging platform without the capability to upload images and files.
Did you even bother to read http://wordpress.org/about/features/ ?
And you can technically make more than 1 level 10 user by editing the database, but it’s pointless as level 10 and level 9 users share the exact same permissions.
