The 8th Gym Leader is Giovani (sp?) a.k.a. the leader of Team Rocket. He lives in Viridian City. You have to beat Team Rocket in every place they are (the Pokemon tower, silph co., game corner) and then of course battle the 7th leader/the fire leader (haha forgot his name). The gym in Viridian City then should be unlocked and you can go inside.

the 8th gym leader is Giovanni and u can only battle him after u beat blaine and go to one island wif bill
The 8th gym leader is in Viridian City.
The sixth gym leader,Sabrina, is in Saffron City.
The fifth Gym Leader in Pokemon LeafGreen is Koga, the leader of Fuschia City's Gym. He specializes in Poison-type Pokemon and hands out the Soul Badge.
Viridian City, Giovanni(Team Rocket Leader) is the Gym leader.
Step on the portals until you get to the gym leader.
It depends on what gym you are talking about all of them you can get to by going to the towns.
You get it from the Fuschia Gym leader
Yes.
The 6th Gym Leader of the Hoenn region (FireRed/LeafGreen) is Winona of Fortree City (or Nagi of Hiwamaki City in the Japanese versions). She is the Flying type trainer and gives out the Feather Badge. The Feather Badge allows the move Fly to be used outside of battle and has pokemon obeying up to level 70.
Once you battle a gym leader you can not battle them again this is the same for all pokemon games unless you want to start the whole game over again but as soon as you get the badge you can't battle any gym leaders you already beat
