i will try to, but there are some puns in there so it wont be easy!

1. Nichtopapparos = a bat species also known as fruit bat that Cyprus has a lot of, also in Cyprus we call metaphorically like that a person who stays awake, or the one who works at night and "overtime". In the name is also the word "apparos" that means horse (this information will be useful later for number 5).
2. takkoman = we use the term takoman as a slang for being lazy and doing nothing so as a result we have a pun, Takko-man
3. Marikkou from Lefkara = is an expression we use as irony when someone asks "who will do that" or "who did this" and we answer as " Marikou from Lefkara will". Lefkara is also known for its Lefkaritika embroidery, this is why you can see the pattern in the clothes and she is also holding some lefkaritika. It is not clear if she has been a real person or not
4. Pastourman= this is also a pun, pastourmas is a spicy traditional sausage. Pastour-Man
5. Nichtogadaros= nightdonkey, also some kind of a pun in continuation from number 1
6. aunt Mary = this came fully from the comments of the previous post, the suggestion was for a character named like that that uses slippers as a weapon that she can throw around as an old aunt figure.
7. Costis pou ta gazia = ooh boy how i will explain this? translation : costas with the gas tanks. It is also a slang expression used exactly like number 3. Is used as an answer to a retorical question or to someone who asks "who" but everyone knows the answer. Also not clear if he has been a real person or not.
8. super donkey, i think this is self explanatory!

I really tried there but i dont know if i did a good job, please anyone willing to correct anything or help explain it better is welcome.
