Can dock items be added for multiple OS users?
You can script dock additions, but it's actually quite a pain to do correctly and in a general manner.

The time it takes you to read one of the links I will add will be longer than it takes to just log in to each user, add the icons to the dock by hand and then logging out.

The above link is a command line utility to manipulate a user's dock. It also can operate on multiple users at the same time, so I would start with that tool and look for others if this one doesn't work for your needs / abilities.

dockutil --add /Applications/Word.app --before 'System Preferences' --allhomes
