I recommend starting with the Evillious Chronicles and look at the timeline for different characters if you want to know chronology. ;) Also, which PV? There are many fan PVs with personal interpretations added on. You might be confused because you are going by what a fan is adding their spin to (happens a lot with Story of Evil songs too).

Kagamine Len has not appeared in any official canon material. You may want to look at Hänsel, Pollo, and Lemy regarding reincarnations with Len characters. It may also help to look at Gretel, Arte, and Ney.
