LED Circuit:: First row doesn't light
The LED's aren't illuminating because there is only 2mA through each group of 3 LEDs when using 1,800 ohm resistors.

Observe just one branch of your parallel circuit at a time. The voltage drop across each LED is 1.8v. 

3 * 1.8 = 5.4v 

There is going to be a 5.4v drop across a group of 3 LEDs in series.

Seeing the supply is 9v:

9 - 5.4 = 3.6v --> 3.6v remain to be dropped across each of the series resistors.

You want 20mA = 0.020A through each series branch. Using Ohm's Law: V=iR

3.6 = 0.020R

R = 180 ohms

Perhaps you used 1,800 ohm resistors due to a calculation mistake. Using 1,800 ohm resistors, only 2mA flow through your LEDs, which is not enough to visibly illuminate them.
