You can get groudon in Pokemon soulsilver and kygore in Pokemon heartgold (both are found in the embedded tower on route 47).
The radio tower is found in Goldenrod city, and Lavender Town.
You can only get Groudon on SoulSilver. Kyogre is found at the Embedded Tower on Route 47, near the Safari Zone, after defeating Red on the top of Mt. Silver, receiving a Kanto starter from Prof. Oak, and getting the Blue Orb from Mr. Pokemon on Route 30, above Cherrygrove City, in that order. After capturing the Kyogre on HeartGold, you can take it to Prof. Oak and find out about Groudon. It will only appear to people with "shining-silver spirits," meaning it can only be obtained on SoulSilver. If you manage to find someone willing to trade you their Groudon from SoulSilver, you can take both Kyogre and Groudon to Prof. Oak and receive the Jade Orb from him, allowing you to find Rayquaza at the Embedded Tower. Please note that if you get your Kyogre or Groudon via Pal Park or from any game other than SoulSilver, meaning that the game and location you obtain either of these Pokemon from, must be SoulSilver and Embedded Tower(Groudon) and HeartGold and Embedded Tower(Kyogre), Prof. Oak will NOT give you the Jade Orb.
Okay. First, get the red orb from Professor Oak. Go to the embedded tower and capture Groudon. After that, have a friend with HeartGold trade you a Kyogre found in HeartGold. Then, put both in your party and go to Oak. Oak will give you the Jade Orb. Now, go back to the Embedded Tower and capture Rayquaza!
Rayquaza is a legendary Pokemon found in the Sky Pillar in Pokemon Ruby, Sapphire, and Emerald. Rayquaza can also be found in Pokemon HeartGold and SoulSilver in the Embedded Tower when the player has the Jade Orb.

Dusclops can be found in the Safari Zone in Pokemon Soulsilver. The rarity varies.
Darkrai is an event Pokemon, and cannot be found through normal game play. Darkrai thus cannot be found in SoulSilver. Darkrai was an event Pokemon that was available for Diamond and Pearl, but not for SoulSilver.
Cubone can be found in the Pokemon Tower (aka Lavender Tower) in Lavender Town. There is a 5%-14% of finding a cubone depending on which floor you are on. 24 is the highest level that you will find them. In the Japanese version of Pokemon blue, cubone can only be obtained through trading.
