Do you mean by displaying an infoWindow when markers are clicked?
If that's the case you may create infoWindow with the information and
then attach it to the marker. That for each marker.
e.g:
var map = new google.maps.Map(document.getElementById("map_canvas"),
myMapOptions);
var marker = new google.maps.Marker({ ...marker options
});
var infoWindow = new google.maps.InfoWindow({
content: 'The message that will be displayed when clicked'
});
google.maps.event.addListener(marker, 'click', function() {
infoWindow.open(map, marker);
});
Hope it helps.
