Assuming you used titanium backup, it is safe to restore all user apps and data. However, DO NOT restore any system apps. It is sometimes safe to restore data only
to some system apps such as the messaging app, but use caution and, if in doubt, don't restore data to any system apps. If you need to save text messages, use the built in backup function (from the menu of the messaging app).
It's also usually safe to restore data to the contacts app, but Google usually backs up all contacts to your account and automatically restores them.
The most important thing: DO NOT restore system APKs.
