    Looks like it might be mealybugs

    Possibly powdery mildew

    Definitely fungal, probably mold or powdery mildew. Check the roots for rot (if that's the case, take cuttings and try to restart the plant; root rot tends to be lethal in succulents.) If the roots are healthy, cut away the worst affected sections and treat the rest with fungicide. Increase air flow and avoid overwatering to prevent future issues. (And you may want to take a cutting from a healthy section anyway, just in case)

    I agree with the others, but I would add that the powdery mildew can spread so be sure to move it away from your other plants.
