Free up space on Motorola Мото Е
Even if you could remove them, that wouldn't free up space in user-data (pre-installed apps are stored in a separate partition the user has no write-access to).

What you could do, however, is go to Settings › Apps, switch to the "All" tab, open the entry for each of those apps, and see if you can "uninstall updates" and then "disable" the app (to prevent those updates to come back). Other than the apps themselves, those updates are installed in user-space.
