Yes, you can breed with Pokemon from different regions, just as long as those Pokemon are in the same game at the same time. For example, you can breed a Pokemon FireRed Ditto with a Pokemon Ruby Mareep, just as long as the Ditto and Mareep are in the same region at the same time.
No. Unfortunately, when Pokemon moved from Generation 2 to Generation 3, Pokemon from previous games became untransferrable due to cartrage incompatibility. You can however, transfer Pokemon from Pokemon Fire Red and Pokemon Leaf Green which are the GBA remakes of the original Gameboy Color games.
This is also caused by the lack of EV's, personality values, and location data.
no
Trade Trade from Leaf Green or Fire Red you have to trade it from fire red to sapphire to ruby to emerald!

YES, YOU DUMMY!(after you defeat the Pokemon League and get the Ruby/Sapphire.)

Impossible. But, you can trade from firered/leafgreen to ruby, or red to gold.
You can do this after you find the Ruby and the Sapphire for Celio in Pokemon FireRed. then you can trade with Ruby, Sapphire and Emerald.
Yes after becoming Pokemon champion in both games you can trade but after firered delivers the ruby and sapphire to celio at one island then you can trade.
