1. An occult shop is one that sells items used in magic and mysticism.Originally Posted by Jenny Lau
I have not heard "odd shop" as a type. It could mean a "strange shop" or shop that is uncommon, as in "the odd shop will sell widgets."
I suspect that "junque shop" is a name, because they have played with the spelling of "junk".
2. I haven't a clue.
3. paraphernalia (it is rarely pronounced with the second r, though that is the preferred pronunciation)
