Yes, you can do it any time with HM dive

Depends on what Pokemon they are and what moves they have and depends on what your doing in the game like in ruby and sapphire if you enter the battle tower you can only enter 3 Pokemon choose 3 of your best Pokemon.
Doing the Pokemon League over and over is a great way for experience and money.
There is no way to become the Pokémon League Champion without doing anything unless you have a friend battle the Champion for you.
The only way to get Lileep in Sapphire without trading is to pick the Root Fossil in the Route 111 desert and take it to the Devon Incoporation in Rustboro City. Unfortuantely, doing this means it's IMPOSSIBLE to get Anorith without trading.
in order to get him to move, you have to go back to island 1 and complete the quest given to you by bills friend. he will ask you to get him a Sapphire and a ruby which, in doing so, will link your game with the Pokemon from Pokemon Sapphire and ruby. this is just for leaf green and fire red.
after you beat the Pokemon league you kick the tv up stairs and rotom will appear at lv 20!

Example you trade a Rayquaza (Pokemon Sapphire) for a Rayquaza (Pokemon Ruby) at LV 70 once Rayquaza you received from Pokemon Ruby will gain boosted EXP points every time. And the same goes to the Rayquaza that was transfered into Pokemon Ruby. Traded Pokemon grow much faster in trades than normal.
It's just an ordinary place. in there you can find lots of items and trainers to battle. But to do that first you have to complete a mission from a professor that doing a research in there
