Spark Plug Help

Awesome site. Wish I had found it before I bought my AU S1 Forte especially since I paid to have some work done on it (brakes - really wished I had known about the upgrade and exhaust rusted out) but no used crying over spilled milk. I am an expat from the US and I wanted to get something I couldn't get back home so Falcon it was! Anyhow the car has very suspect history as of the last 5 years. Prior to that, it was serviced well.
I just changed the plugs and as it is the first time I've done it ever, I was looking for help interpreting them. Apologies in advance for the ****** pics. First I'm confused since the plugs don't seem to have uniform deposits. They have them on one side... Is that normal? Second, plug number 5 had a wet oily brown coating but not on the top but near the threads. What does that signify? By number 5 I mean the plug is the fifth from the front of the car on the I6 or second from the dash.
Thanks.
