Starting with the second photo, the hose with the red square is a fuel vapor vent hose and should go to the filtered side of the air cleaner.
The green circle is an engine vacuum port that could be used for your power assisted brakes if you can locate a fitting that the hose will fit onto and still screw into the manifold.
The red circle in the first photo is a vacuum fitting, what you need for vacuum advance is ported vacuum. To check for this run the engine at an idle and test for vacuum there should be none, but when engine speed is 1500 to 2000 rpm you have vacuum this is ported vacuum.
The reason why you want it this way is so that you don't have full vacuum advance at idle, and so that the advance starts to increase as engine speed increases.
Hope that this makes sense.
