Is having multiple characters something to aim for? Do they share the same Eternaland?

As title says is it worth making a second character while I wait for the next phase.

Actually, each-one of your characters have its own Eternaland... So, you should avoid playing on multiple characters.
Plus, changing your name cost extra money, and you can't name all your characters the same.
