You can use the same Apple ID on all of your devices (and that is usually recommended). You can sync the devices by turning on the options (on iPhones & iPads) at Settings > [username] > iCloud > Photos, iCloud Mail, iCloud Drive, Contacts, Calendars, Notes, etc) and the similar options on a Mac at Apple menu > System Preferences > Apple ID > iCloud.
