Generally yes but is subject to passport/visa issues of the country you are in. Beware there can be a cost difference (taxes) between a transit vs stopover. So its best not to tell check in agents you are leaving the airport as they may think you are making a stopover.
What airport would this be? [have not looked at your itinerary in detail]
