yes it is as long as the cetain accessorie will fit an ipod touch. iPod touches must have special cases, but things like headphones or iHomes will work with the iPod touch like any other iPod. BUT, some accessories won't work. Such as the iPod camera connector.
no the first is thicker and wider
Yes it will fit but not perfectly but you can put it on
Possibly, possibly not. If you have the first generation iPod Touch, it will definitely not fit. If you have a 3rd generation iPod Touch, it will most likely fit.
. The iPod touch 4G is slightly longer than the previous iPod touch 3G
Different Ipod Touch accessories 3rd generation exist, and new ones are typically being developed often. There are still many people who own these devices, so it is worthwhile for companies to manufacture accessories that fit them. You may want to buy chargers and cases that fit your Ipod well, instead of trying to buy a case that is too big or a charger that does not work right with your device.

Yes
if you are talking about a case it would depend on what generation the iPod touch is
no
