1.Only

Answer 1

According to android developers permission-group:

Note that this element does not declare a permission itself, only a category in which permissions can be placed. See the <permission> element for information on declaring permissions and assigning them to groups

You would need two permissions Manifest.permission:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />

to be able to access the camera and the flashlight.

And you would need to declares the hardware features that is used by the application (camera and flash) Features Reference:

<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-feature android:name="android.hardware.camera.flash" android:required="false" />

android:required indicates whether phones not having these hardware can install your application or not.

On your third point, I think you have a type because uses-permission tag can not be used with android.hardware...

<uses-permission android:name="android.hardware.camera.flash"/>

Answer 2

Maclir answer is showing all the detail of permission required to use camera and its flash light. you can also use these two permission to use flashlight in your application.
