We know Chrollo loves books. I can't see Nobunaga as bodyguard, but as a mercenary. He is inspired by samurai so he must like practicing iaido.Just for fun, what do you think Troupe members doing in their free time?
I can see Machi as a part-time embalmer, obviously. Nobu as a bodyguard. Chrollo maybe doing volunteer work for an orphanage. Phinks and Fei just doing whatever they want. I can also imagine Shizuku work as a librarian
Same for Shizuku, I can't imagine her as a librarian. I think Togashi wanted to draw someone who looks like a normal person but how is anything but that. She seems to like mangas (she is the one who said Skill Hunter is like the Death Note) but I don't see her reading general books.
Feitan and Phinks seem to be adrenaline junkies. When we saw them in the flashback Phinks was on a bike, both also love video games. We saw Feitan reading a torture book. He is probably a weapons nerd.
Machi gets money for stitching people so she has a side job(not sure if being a PT member can count as a job but still).
Franklin is big and gets heated in battles but is also cool-headed in general and seems to have good emotional intelligence. I'd expect something uncharacteristic for his build, which requires patience and precision, like knitting or something. He could be a tattooer, piercing artist or into arts in general. He modified his hands for a power boost after all.
