The legend rule only cares about multiple copies of the same card. There's no limit on the number of different legendary permanents you can control.

Could either you find any legal statements proving that? I'm gonna need it.

704.5k If a player controls two or more legendary permanents with the same name, that player chooses one of them, and the rest are put into their owners' graveyards. This is called the "legend rule."
This is the rule that causes legendary permanents to be put in graveyards, and it specifically calls out that they have to have the same name. This references rule 201.2:
201.2. A card's name is always considered to be the English version of its name, regardless of printed language.
201.2a Two objects have the same name if their names are identical.
201.2b If an object has more than one name, it has the same name as another object if there are one or more names that both objects have in common.
201.2c Two or more objects have different names if there are no names that both objects have in common.

As far as your ability to have different legendary permanents, you won't find a rule explicitly stating that. The rules exist to define limitations, restrictions, and processes. They don't catalog everything that you're able to do. In this case; the lack of a rule saying you can't is probably the proof you want.

Works for me! Rules say there cannot be 2 of the same legend under my control. Says nothing about having different ones in play.
