The lighter is there to make sure that you use and manipulate fire that doesn't or hasn't been made with chakra. See if you had an open sourced fire that doesn't have chakra in it it would work just as same as if you used a lighter. Also the hurricane fist is a jutsu in fuuton[wind release] Basically a punch that is infused with wind chakra.
Moving on! O__O
( Katon: Ryūka no Jutsu ) - Fire Release: Dragon Fire Technique
For this technique, first notice the hand seals as you are required to perform them before using this technique. Still a flame version of the fire itself so the concept is still the same, though it is a bit slower to perform this jutsu because of the hand seals. However, you will need to trap the opponent with a wire before even attempting to use this jutsu.( Katon: Honoo no Saigai Hi Kagayaku no Jutsu ) - Fire Release: Flame of Disaster Fire Shine Technique
This one is quite interesting I would say. A stream of fire that wraps around the opponent! How do you think this is possible? After finish replying, at the end for this jutsu, post a picture.
