Whenever I drain my compressor only some droplets come out and I find that strange so today I opened the drain valve and I tried tilting the compressor and brownish/orange water came out, the compressor is a stanley one bought it in November (its new). Is this normal, should I always have to tilt my compressor to drain the water?

Without a picture I am guessing, but it sounds like the "something connected above the air valve" is your pressure vacuum breaker. A pressure vacuum breaker prevents water from flowing from the outside back into your main water line (and then into your drinking water). It will allow water from inside your water main to travel through it with the water pressure from your house forcing open the pressure vacuum breaker (while water traveling in the reverse direction closes the valve and prevents contamination of your drinking water).
It does sound like the sprinkler water main has a very slow leak. And I imagine a slow leak from your sprinkler water main is not enough to completely open the pressure vacuum breaker and it is just exiting at this point (when the air valve is closed).
I'm not sure what the rod might have been, the inside of an air tank is pretty simple.
Replacement drain valves are available in a variety of configurations, and generally they thread into a nut welded into the tank. It's then just a matter of finding an appropriate replacement valve (relatively easy) and removing the old one (probably much harder).
To help get the frozen valve out, you could (should) try penetrating oil to free what are almost certainly frozen threads, but you may need to step up to using a torch to apply heat to help break the part loose.

If the drain isn't at the bottom of the tank, then yes it's normal and yes you should tilt the compressor to correct that before blowing out the water.
