Help reading spark plugs

[AlaskaTy]

Well, I pulled my plugs and ohm tested my wires (plugs and wires are about 2 months old with approximately 20 miles on them). They all had about the same resistance (if I did my math right it was about 154 ohms per foot) but 2 of them (#3 and #6) had to be rebuilt because I wasn't getting a good ohm reading out of them initially. So there's a chance that I had a couple of dead or impaired cylinders.
The plugs had a huge difference in appearances:
#1 fouled
#2 fouled
#3 looked brand new
#4 fouled
#5 Looked brand new
#6 the electrode (metal that overhangs the center electrode) was whitish in color and it was slightly fouled.

any ideas why some are fouled and others look like they just came out of the box? Anyone?
