the fourth gym leader is you DAD in petalburg city!! It ain't Daddy, Pa's the 5th gym leader. Actually, its Flannery. Look it up on pokemondream. You have to go to mt. Chimney, battle Team Magma/Aqua, and go back on the jagged path. It takes you to Lavaridge city. The gym leader has two Slugmas that are easy to beat and a Torkoal that knows Overheat. And by the way, the 5th gym leader is your dad. I know because I'm working on the 7th.
How to get to Lavaridge- in order to get to lavaridge town, you must take the cable car up mount chimney, go south near the old lady selling lava cookies, and climb down the Jagged Pass. once you reach the bottom, go east and you'll find yourself in Lavaridge town.
Navigating the Gym- i am currently on Pokemon emerald, ruby and sapphire may be different from this. don't use the portal next to the door, but go north of it, than use the western most portal, than the northwestern most. once again go northwest, and ONCE AGAIN go northwest. go through the middle hole, than take the southeast hole. jump over the ledge ONCE, because if you jump over two ledges you will miss the portal next to the right wall. now you are in flannerys room! she has a lvl 24 numel, lvl 24 slugma, lvl 26 camerupt and lvl 29 torkoal. this gym isn't TOO hard, but it will require a few tries at it
go north of mauville city turn left at the desert go up to the top of the stairs you'll find defeat team aqua then get on the cable car go through the entrance go to the bottom exit and there is the town
mauvile and the fifth gym leader is in petalburg
go back to petalburg city (go to slateport then sail with mr. briney to dewford then from dewford to petalburg with mr. briney.) The 5th gym leader (your dad, Norman) is at the end.

It is not a selectable Pokémon in Ruby. If in doubt as to which characters are "4th generation" you can consult the Pokédex website. Gible didn't exist in the original Ruby game. In Pokemon Omega Ruby, however, you can catch a Gible (as a Hidden Pokemon) on Route 111.
Well you can't find them all in 1 place ,but all I know that is its up to the 4th gen
You can't because darkrai is a 4th generation pokemon
The leader is Falnery, she uses fire type pokemon.
There is no HM Defog on Ruby, it came available in the 4th generation which is Diamond, or Pearl.
