What you see above burning matches or wood is not plasma, but just glowing carbon particles.  When burning gas (like methane, propane or butane)you have fewer carbon particles because this gasses have more hydrogen in their molecules than the cellulose which is the main component of wood.

Plasma (http://en.wikipedia.org/wiki/Plasma_%28physics%29) is ionized gas.  Plasma is matter - or rather a state of matter.
Fire (http://en.wikipedia.org/wiki/Fire) is a phenomenon, related to a rapid oxydation process.
You can have plasma without an oxydation process - rocket exhaust gas may be the only case where such a process is important. 
There is one example of plasma known as "St. Elmo's fire" (http://en.wikipedia.org/wiki/St._Elmo%27s_fire) but that is not fire in the usual sense of the word.

Yes the fire above a matchstick has some aspects of a plasma and conducts electricity because some of the atoms are ionised.
