Question

How many Krueger flaps does the 737-700 have? It has inboard krueger flaps, but I'm trying to make out if it has one or two.

Answer 1

It has 4 Krueger flaps (2 on each wing) and 8 slats (4 on each wing):

LE devices consist of four flaps and eight slats: two flaps inboard and four slats outboard of each engine.
