Normally, no. The DNA in all of your cells is the same. Any cell that has a different DNA is recognized by your body as foreign and is attacked by the immune system. That is why people who get organ transplants have to take drugs to suppress this response, and why the placenta in a pregnant woman prevents the mothers body from attacking the baby.

Yes! If you watch CSI a lot they actually have episodes in these weird cases. Chimerism and bone marrow transplants (as well as other transplants...) are examples of where an individual may actually have more than one set of DNA.

I think it was discovered recently that a person can have some organs with different DNA than the rest.

Not sure exactly what you're asking.
People have two of each chromosome, two sets of every DNA strand, two sets of every gene.

If "normal" and "cancer" is considered "dual DNA", then yes.
