Well if you go to best buy or something the case's package will usually say what gen it fits.
No it can't. An iPod touch 4th G is to short to fit and a 5th G case.

You can purchase a clear silicone case for the iPod touch 4th gen at case-mate.com, otterbox.com, apple.com, touch-smartphones.com, and I would assume many other online sites.
No. Although it is possible that it would fit, the camera that is on the 4th generation ipod touch would be covered up with a second generation case.
It depends, if it's a hard tight fit case, then no; if it's a soft rubber case, then it should.
No they do not. The Ipod touch 4th generation has a completely different case then previous models.
yes...the 4th generation 8GB iPod touch has a camera
