There is no special trick needed. You simply need a compatible webcam (most are) and software that makes use of it, such as Cheese, a Flash game, or a chat client (such as Kopete or aMSN).
Most Logitech webcams are supported by Linux.
It depends on the brand of webcam, whether it is built in or not, and if you are using Mac, Windows, Linux, etc.
You don't. All webcams that Linux Mint is capable of supporting have drivers installed by default. They are included in the kernel.
You cannot use a Webcam as a projector. A webcam is an input device, not an output device.
There is no "Linux messenger." There are several clients available for Linux, however. The most popular one, Pidgin, does not support webcams. aMSN (for Windows Live Messenger) and Kopete (for all protocols) does. Virtually all webcams are supported out of the box in the Linux kernel, so no extra work is needed, other than to use a capable client.
how can i use my Panasonic NV-GS47 as a webcam
I'm not sure why you would want a fake webcam app, but the Chromebook already has a default webcam. See the related links if you want to test to see if it's running properly.

Sorry but no you cannot use webcam toy on your phone.
Yes.
Just plug it in, and use an application that supports webcam functionality.
Certain camcorders can indeed be used as a webcam. For further instructions you can visit http://chris.pirillo.com/how-to-use-a-camcorder-as-a-webcam/.
