oh, this is a really good question! so, it doesn't refer to them as lunarians directly, but it also doesn't refer to them with any other proper name. in the official, judging by the @opbackgrounds post, it looks like they've called them 'mooninites.' in japanese, it just calls them 月の人/tsuki no hito, meaning "people of the moon." which reads as a descriptive term, not necessarily a name. the full phrase translated directly would be like "winged 'people of the moon' who lived in ancient times."

the name of the lunarians is spelled out directly when they're eventually named as ルナーリア族/runaaria-zoku, with 族/zoku meaning 'tribe' or 'clan.'

while we're at it, it may be a coincidence, but i will note that marco's memory of whitebeard's story of the ancient civilization on top of the red line (in the same chapter the lunarians are named) refers to it as 神の国/kami no kuni, 'country of the gods,' which is also a term used to describe skypiea a few times throughout that arc.

this is. so wrong. on so many levels. it's almost funny except not really and i'm just laughing because being angry is exhausting ajshdjkfds

i'm sorry i keep being a killjoy who can't take a joke but!! this is so against javier's character!! javier would never do something like this his entire deal is about how loyal he is and how protective he gets with the people he cares for!! he wouldn't put lloyd in danger for his own amusement!!

even at his pettiest, and god knows he's a massive brat with lloyd, he's still always on guard for whatever may threaten his life that's literally his major priority, something he takes very seriously!!

heck even in this very arc we get a little glimpse of how javier thinks!

I must play my part here without any mistakes. Javier remembered how Lloyd had come to Hell because of his trust with him. So, he could not let Master Lloyd down. He had to get the job done, even if it was dangerous. Javier believed that was his primary duty while escorting his young master through Hell, to begin with.

what part of this gives any indication that javier takes his duty of protecting lloyd lightly. much less that he enjoys seeing lloyd be in danger.

not to mention what they did with the lava giant asking if he really wants to protect lloyd and javier actually has to think about it

like. c'mon.

contrary to what i may look like i actually do know what a joke is i get it they're just being funny. however. there's a saying in spanish, 'entre broma y broma la verdad se asoma', meaning 'between joke and joke the truth appears'. you can only joke about something so much before people start thinking you're for real. and making javier constantly act like he doesn't give a crap about lloyd,,, well, it can only mean so much y'know?

which sucks because that's not the point of javier's character. much less in this arc. he cares about lloyd so much, even when he doesn't want to, and that affects almost every single thing that he does. he likes and trusts lloyd more than he's comfortable admitting but at no point in the entire story does he act like he doesn't care about what happens to lloyd.
