To reach Island 4 - 6 (and 7), you need the National Dex from Prof. Oak. This Dex is obtainable after beating the Elite Four and having at least 60 different kinds of Pokémon.

Now, after receiving the National Dex from Prof. Oak, go back to Island 1 (Bill will be at the Cinnabar Island's PokéCenter if you're still in Kanto and need to have a transport to the Islands). Now go inside Island's 1 Pokémon Center and talk to Celio (the guy with his big machine). He will now open a cave in the north.

In this cave the Ruby Gem can be found (make sure you have a Pokémon with you who knows Strength). Return it to Celio and he will give you a Rainbow Pass, which gives access to Island 4 - 7.
