If they are pre-installed apps, you may not be able to delete them. But you can Force Stop them. Go to Settings, Apps, swipe to All, scroll to the apps in question, and select Force Stop.
If they are apps you've installed yourself, you can select Uninstall.
You can also uninstall those apps by long-pressing the app icon, and sliding it to the Uninstall option that will appear.
