The empty circle could be either a black hole system or a nebula system though I could well be wrong there.
The ship Icon denotes that you have a TG in the system, it does not however indicate anything about actual ships (so for example a PDC TG would still show). The lower left icon appears if you have the option to show shipyards checked, and obviously it denotes you have one or more shipyards in that system.
As far as the planet numbers go it depends on how you play with the map settings, there are options to show for example planets between 2-2.9 colony cost. Or others that have different costs. In addition there are option to show planets you have a colony on, or planets with >100m population. If you look through the list in the galactic map you will see all the variations you can apply to show or hide planets & colonies.
