you have to beat the Pokemon league then go to snowpoint city and talk to the man with the boat he will take you to the fight area then go to dawns house and talk to her sister and she will tell you where Pokemon are every day keep on talking to her every day she will tell you eventually that a makuhita is up from the fight area you have to see all the Pokemon in sinnoh to go there then use your poke radar(you get that from professor rowans lab)keep on using it until you see makuhita(make sure you buy poke balls before you catch it
I believe you have to have six Pokemon chosen to migrate them to pal park in Pearl. If you don't have six Pokemon you want to migrate, then catch however many Pokemon you can trade.
As many as you want, But you can only migrate up to 6 PokeMon a day.
It doesnt matter how many times
You can find out how many times you have beaten the Elite Four in Pokemon Diamond by checking your PC in the game.

One each.
Chimchar evolves twice in Pokemon Diamond Version. From Chimchar to Monferno to Infernape.
13 times or more
They're are many ways to get or catch a water Pokemon in Pokemon Diamond. You could get a fishing rod from a fisher man, obtain the HM Surf and use above water to encounter a wild water type Pokemon, trade someone or migrate a water type Pokemon from your old GBA games. Peace.
six
it is not exactly called trading. if you have both games that are yours, you can migrate your Pokemon. once the palpark opens in pearl then put Pokemon leafgreen in your ds with pearl in it. (the leafgreen game must be gba). you must have more than 6 Pokemon in your PC to migrate. the Pokemon you migrate can`t return to leafgreen. then once the games are in, go to pearl and on the menu you`ll see migrate. here`s a tip. migrate super strong Pokemon. then beat the elite four many times. if any questions, contact me.
Many Johto Pokemon can be found in the wild. If you have the National Pokedex, just search up the specific Pokemon on there, tap 'Area' to see where it lives, and catch it there. If it doesn't live in the wild, you'll have to migrate, trade or cheat to get it.
