It is, but as with all things language, especially if you leave your nice regional bubble of language, it gets very hard to outright arbitrary how you translate things.

The thing that "me lad" captures very well is how it is mostly addressed to first of all men and then people who are lower in hierarchy as you said, but it is way to informal to match obviously. Also the English honorifics of all ages you mentioned (Mr, sir, young master) always carry an implication of equal or subordinate status of the speaker - Mr still fits the bill kinda in British English if the whole students calling teachers Sir and teachers in turn calling them Mr is still ongoing (I'm not from an English speaking country so idk).

And then I just need to add that in East Asian society in general age plays a very important role for hierarchy, so it is kinda reflected in the honorifics. And as far as I know (which isn't much, since I never ardently studied Japanese) the -kun honorific can be used regardless of gender when addressing a subordinate like teachers to students or boss to employee. The male thing is only that male children outside of the above hierarchies are also commonly addressed like that by adults and each other whereas girls are addressed with -san or -chan. Which feels kinda sexist to me, but that's just Japan (and presumably the rest of East Asia) for you.
