In the module Air density, The value for the air temperature is set to 59 deg F which is the standard temp condition at sea level. If I am at a place above sea level with different air temperature then do I set it to the current air temperature of the place I'm at?

Air density decreases roughly 1% for every 100 m or so above sea level. This is just a rough estimate but close enough. Air temperature won't matter as much as you should have an intake air temp sensor(may be built into MAF if you are utilizing one) that will adjust the calculation on density
