What are humans created from?

Q: In the Quran Paak 15:26 man created from mud (I translated in my own words please check reference) while 21:30 every living thing is created from water (again my own words please check reference). Please tell about these two verses and also, jinat and angels are created from fire and noor? 

Forcing one's husband to issue a talaaq

Q: I'm a 33 year old woman. My husband was an alcoholic. One day we got into a heated argument and I couldn't control myself and forced my husband to give me talaaq. He refused at first and kept quite. When I forced him he just told me "Go talaaq" just once and he repeated the same thing after somedays. I want to know if talaaq took place in this situation and how many?
