Connect 1 power source to 2 sets of 2-light switch
Ascii, nice.  There's many ways to wire it depending but this is the most straightforward way to illustrate it:  

Source ---blk--- Switch ---blk--- Light1 ---blk--- Light2 ---blk--- Light3 etc.
       ---wht---        ---wht---        ---wht---        ---wht--- 


The idea is that although the lights are electrically in parallel, the wiring "daisy chains" from one to the next.  The switch can tie into the chain at either end or in the middle, it doesn't matter.  

Now with two switches, it gets a little more interesting - you want different kind of switches, and three wires plus ground between the switches.  (No more asccii, going to reuse someone elses drawing...)
