Each Pokemon has a type and different types match up to other types in different ways, so there is no strongest Pokemon- it's all decided by types. eg. A normal type legendary may be defeated by a small general fighting type.
18, one for each type
There is no such thing, BUT.. you can do each Pokemon one-by-one
neither of them is better, they are both the same, but in diamond, you catch dialga, and in pearl, you catch palkia, and you can catch different Pokemon in each game for example: you can catch this Pokemon in diamond, but not pearl but: you can catch this different Pokemon in pearl, but not diamond
The top fifteen Pokemon across all of the games are as follows.Name:ArceusMewtwoLugiaHo-ohRayquazaDialgaPalkiaGiratinaGiratinaSlakingKyogreGroudonRegigigasDragoniteMew
One each.
Do you mean trade from Diamond to Platinum?? If so, you need two ds's and a copy of each, sorry bad answer.

You can get it by talking to Dawn/ Lucas's sister in Pearl or Diamond. Each day they tell you a different species of Pokemon is swarming, and where to find it. The Pokemon changes each day, so Cubone will eventually be swarming, if it isn't today.
based on luck, while catching Pokemon check each time for that nature
Each Pokemon diamond game has a different ID. You can find the ID by looking at the numbers in the lower left corner of your game cartridge.
No, each game version is unique and require differnet codes. if you need codes for Pokemon Diamond just Google it.
