In a dictionary, words are compared letter by letter from the left; the first place where two words differ decides which comes first. Find the dictionary order first, then reverse it.
All five begin with vha; the fourth letter is b in words 1 to 4 and d in word 5, so word 5 comes last
Words 1 to 4 begin with vhabg; the sixth letter is h in words 1, 3 and 4 and k in word 2, so word 2 comes after them
Words 1, 3 and 4 begin with vhabghe; the eighth letter is a in words 1 and 4 and c in word 3, so word 3 comes after them
Words 1 and 4 begin with vhabghearhb; the twelfth letter is v in word 1 and u in word 4, so word 4 comes before word 1
Dictionary order: 4, 1, 3, 2, 5
Reverse order: 5, 2, 3, 1, 4
The sequence is 52314.
