Google Maps V3 Overlapping Markers on exact Location

I am having issues with markers overlapping, please do not down vote as I am not highly schooled in javascript also I have looked at the different answers offered on stackoverflow but have not been able to use them to find a solution so please help! The code is grabbing php for lat and long based on static points I have given I would simply like to list all of the information in the same marker rather than have it overlap markers any help would be highly appreciated here is the code:
