I’m not quite sure what you want to end up with.
But first of all the following:
To see a calendar of a user you have to have (at least) read rights.
You will have to deal with the calendar settings. There you can and must adjust a few things if necessary.
Also have a look at the planner view for users.
Finally, you can create the view(s) as favorites for the group. Then nobody has to worry about how to get the view.
If there are more specific questions, please open a new topic. Please do not open more than one topic at a time!
Maybe it also makes sense to invest in professional support for this topic. @EGroupware-Italia speaks Italian and could probably explain it quickly via screen-sharing. His website: http://www.webtrain.it/
