any headphones with a miniature jack (3.5 mm, not the biggest (6.35mm) and not the smallest(2.5mm)) will fit into an iPod touch.
Yes.
It depends on the accessory you are talking about. The headphones will still fit into the 2nd generation, but a case will not.
yes
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.
Yes !
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

No, an iPhone cover cannot fit an iPod Touch. The iPhone covers are slightly larger than the iPod Touch, so the cover would not fit.
No it can't. An iPod touch 4th G is to short to fit and a 5th G case.
Yes
if you are talking about a case it would depend on what generation the iPod touch is
