Image of Japanese Equivalents for Western "Ranks/Titles"

Everyone, are you familiar with the specific powers, size of territories, and social positions of Western nobility titles? Even if you know about the five-rank peerage system—Duke, Marquess, Earl, Viscount, and Baron—and their names, isn't it true that your mental image of their actual content remains somewhat vague and unclear? So for us Japanese people living in the modern age, to make it easier to understand and visualize, I've attempted to convert and calculate these titles concretely by applying them to modern Japan. With this, both territorial nobility and clerical nobility (who serve as bureaucrats) should be able to understand and visualize their standard approximate social positions according to their ranks. Probably. Anyone with work experience or who's a salaryman should get it, I'm sure. So please, feel free to use this as a reference.
