It can, and using it while it's charging won't hurt it, but sometimes it's difficult to use the Kindle Fire while it's on the charger. This may depend on your version of the Kindle, but there are some that are glitchy and difficult to use when they're being charged.
yea.
A charging cable, and a match for the fire if you get bored.
no you don't have to but if you want to use it while it is charging then you can
I don't believe the Kindle Fire supports Qi charging at this time.
When your Kindle is charging, you should see a lightning bolt symbol on the battery icon in the top right corner of the screen. Additionally, the indicator light on the bottom of the device will turn amber when charging is in progress. If your Kindle is plugged in but not charging, try using a different charging cable or power source to troubleshoot the issue.
Some sizes are not compatible. You would have to check and see if the jack is large or small enough to fit into your kindle for charging, be advised you may damage your kindle and adapter if trying to make it work
Yes, you can use it while it is plugged in.
If it is an iPod Touch, yes, you can work on an iPod or use the iPod while it is charging.

Of Course! You can preform any function on a phone while charging, including calling and texting!
