to get an egg, breed two Pokemon one male and one female- that can breed with each other. like for example- Empoleon and espeon. if you leave the two in the daycare and ride up and down on your bike, they should breed an egg, either a piplup or an eevee, depending on the Pokemon's gender. if you can't find the daycare, it's in solaceon town. HTH :]
you get the manaphy egg in Pokemon rangers and send it into Pokemon diamond or pearl
You get a togepi egg in Pokemon Platinum, not Diamond.
Have two Nintendo DS one have the Pokemon Ranger and one with the Pokemon Diamond. Then go to check egg. Then you have it.

It is not possible to get a Lugia egg in Pokemon Diamond. It is generally impossible to get an egg of a Legendary Pokemon the only exceptions being Manaphy and Phione.
Manaphy is obtainable in Pokemon Diamond if you also have a copy of Pokemon Ranger. The game Pokemon Ranger is able to communicate with Pokemon versions; Diamond, Pearl, Platinum, HeartGold and SoulSilver to transfer a Manaphy Egg to them. This Egg can be hatched like any other Pokemon Egg.
