If decoherence matters in 2 different observables

    ¿Can´t matter that decoherence matters for 2 distinct observables simultaneously ¿ Maybe the measurement apparatus must been defined clasically in this case

    There is nothing special about multiple observables. You can even construct observables which directly depend on other observables, so decoherence in one has to imply decoherence in the other as well.

    You have decoherence everywhere, all the time, happening in the world.

    But in the case of decohere in various observables, not being one function of other/s, in what observable basis collapse??

    You do not need collapses.
    If you prefer interpretations with collapses: in both. Those observables have to be commuting to get this anyway.
