Answer

You could use a closure. Just modify your code like this:

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
    };
})(marker,content,infowindow));

Here is the DEMO

Question 2

I am trying to add multiple markers each with its own infowindow that comes up when clicked on. I am having trouble with getting the infowindows coming up, when I try it either shows up only one marker without an infowindow.

Thanks, let me know if you need some more information
