You have to enter the Meeting Place which you can only enter after you defeat Venasaur's tasks.
complete the other zones and go to the meeting place(in meadow zone you have to befriend all Pokemon first.)
The Meadow, Cavern & Lava Zones
you can find her in the main aria where you can go in diffrent zones she should be walking around
you usually have to look for bubbles at the top of the zone keepers head but if you already been there,you can talk to drifblim and he will take you there.
You don't specify what type of zones you're talking about, but from the context "time zones" seems likely. In that case, the answer is no. Zone boundaries are ROUGHLY based on longitude, but political factors enter the equation as well (it should be obvious that having parts of the same city in different time zones would be awkward).
No yanmega is not in pokepark but flygon is
Rikou isn't in pokepark
Unfortunately no, you can only be pikachu. However you can play as different pokemon during the mini-games.
