18)Khandra (dead)
19)Mususiel (dead)
20)Nuhj (dead)

3 more weren't active Jedi of the order, but were still hunted down:
1)Ahsoka Tano (status unknown, likely alive)
2)Eeth Koth (dead)
3)Kirak Infila (dead)
So there was a total of at least 24 Jedi and 12 Inquisitors in the Galaxy at the start of the Empire reign. At least 2 new Jedi were recruited and trained after Order 66, but before the fall of the Empire, thus becoming targets of the purge:
1) Ezra (status unknown, likely alive)
2) Luke Skywalker (survived the Empire, died years later)
Luke Skywalker and Naq Med are the only 2 jedi confirmed alive after the fall of the Empire as of now.
