Not much usually. Viking metal is only about Vikings, whereas folk metal can have lyrics about anything. Folk metal often has more "folk" elements than Viking metal too. Compare the bands Arokna (folk metal) with Thyrfing (Viking metal).
Look up Turisas. The song is Battle Metal. Freakin Epic. Celesty are also good, and Ensiferum, although they do growl. Have you tried Cradle of Filth or Dimmu Borgir? They can be a good place to start on black metal (from whence Viking and folk and symphonic metal came) although they've pretty much left the ranks of black metal credibility.
A folk tale is a story, and a folk song is a folk story set to misic.
I would describe Viking art as folk art as it was created before 'art' became a taught discipline. However, it is debatable.
snake doctor is a common folk term for dragonflies
Yup! Lots of it for the richies but not so much for the poor folk.
Korpiklaani is often thought to be the best folk metal band of all time.

Folk Metal
Folk metal, melodic death metal, death metal, METAL.
Foreign music is from different cultures, countries, religions, languages etc. Folk music is very old, and tells a story.
The strongest difference is the musical instruments, Greek folk has bouzouki ( an instrument that I do not know if exists in any other country) and the lyrics are also different, they have different meanings Anyway, it's difficult to tell the differences without hear them both.
