How can you ‘brand’ 5 different websites that live under one parent company that are all very similar with the exception of the demographic? Stack Exchange is a very good example because they sites are all a similar function but with different demographics.
How can I create graphical elements that all relate to each other, but are somewhat different between the sites. They should all still be visually recognizable as part of that ‘family’.
Start with the excellent answers to this question, which is closely related. If you follow the steps I outlined in answer to your other question, then look at DAO1’s and Lauren Ipsum’s responses to that question, you should have all the ammunition you need.
