The star doesn't need to be actual blue but I want it to appear that way from the planet. Cause blue's cool. It could be because it's shining through some nebula it blew off when it died or maybe has a blue ring in orbit around it or whatever.

I count six planets in my proposed list, for Earth according to Wikipedia, there were five classical planets observable with the naked eye. I'm not sure I can read that solar diagram there, does it include moons? As only see four planet orbit rings.
