Install the apps you need to share in your owner profile. When you are at the select user menu, tap "user settings", and select the user profile. Ensure you have not enabled "disallow installing apps", then tap "Install available apps" and toggle on the apps you want to share.
The apps can be installed "system wide", but the app data (local storage) from each profile is a separate instances. For cloud apps, when you log in, they should sync libraries. But you'll still have to set them up independently on each profile.
