In José Manuel, Manuel would be the middle name, just like in English. It's not a "two-words-long first name". Sometimes first and middle names are coupled like a whole, like it's usual for José Manuel. Also for José-something or Juan-something in general. Other times, the middle name is never used, like in Nicolás Antonio, being the Antonio part extra annoying, because the SS personnel, for some reason, insists in calling me that when it's my turn.

My wife's sister decided to name their two newborns with three names, on top of the usual two surnames.

I wish luck to those two little guys, as their names will be misrepresented pretty much in every system in the world.

Wait, what? We don't have middle names, we have "nombres compuestos". Sometimes you may drop part of the name, sometimes not, but you will never see a form with a field for the middle name like you see in English speaking countries.

So different ways of calling the same thing and different UIs. But it's just given names vs. family names and a set of rules. I like Bulgarian ones most.
