They come like that.
Each city which has a gym, the gym will open.
But for saffron you have to finish silph co.
Viridian will open after you have finished the other gyms.
Cinnnabar will open after you have the key (i forgot its name) which you get in the Pokemon mansion.
No, there aren't 9 Gyms in "Pokémon LeafGreen." There are actually 8 Gyms in "Pokémon LeafGreen."
the gyms are in the citys but some are harder to get into than others

NO! You can only unlock pal park on platinum, diamond and pearl
In leaf green you should start with bulbasaur because the first 2 gyms are weak against grass Pokemon
you should get at least a level 60 or up Pokemon and beat all other gyms then he will return in viridian city.
