Could you do a "trial run" through these scenarios?

That is, I'm interested, and would like to see how it's done by the rules, so that I can apply it to my own star-building. :) So if you can provide examples of how you'd go through the rules and achieve these, I'd appreciate it. Even broad instructions would be helpful.

Thanks!
