The misprint is the U in rUde.
I have the overlaps:
Names 1 & 2 make the line overlapping by one letter.
3,4,5 form a loop with the being the longest of those. It overlaps 4 by one, 4 overlaps 5 by two letters, 5 overlaps 3 by 1 letter. That loop also goes thru the common letter in 1/2 and the last letter in 2. There is an unfortunate coincidence of letters in 2 and 3 which mislead one into thinking that 2 and 3 overlap by four letters.
The whole is indeed 22 cells, in a symmetric representation.
Knowing next to nothing about the theme, I wonder if those five characters have something more in common than just being five out of many more stars. And why refer to them as 'characters'?
