Help...

I have to fill in with WHILE and WHEN... Can somebody tell me if I wrote it correctly?
Thanks in advance

1) I found the letter WHILE I was tidying my room.
2) WHEN she was sunbathing, she fall asleep.
3) He was hit by a car WHILE he was crossing the road.
4) I was checking in WHEN I realized I didnt have my passport.
5) WHEN she saw me, she was watering some flowers.
6) The robbers arrived WHILE he was closing the shop.

2) While she was sunbathing, she fell asleep.

All else appears correct (smile).
