Yes, drug tests will usually be able to tell them apart, because they not only look for the presence of the drugs in the body, but the metabolites of them, as well.

And if you are being given a standard urine test, then Heroin can be detectable in them for as long as 5 days, after last usage.

There is, however, no way to give a precise time frame, because it is always going to vary from person to person, depending on individuating factors, such as your overall health, activity levels, metabolism and etc.

It depends on the test- there are so many kinds. Some test only for opiates and some test for specific kinds. 5 panel UA tests will only test for opiates, and what it's really testing for is morphine. So anything which metabolizes to morphine (or morphine itself) will trigger a positive (heroin, morphine, codeine, etc). Synthetics or synthetics derived from a natural opiate which do not metabolize into morphine (oxycodone, methadone, etc) will not trigger a positive.

However, the larger panel tests (like a 9 or 10 panel) will have a separate test for oxycodone and a separate test for methadone. Of course, what it's really testing for is their metabolites. I'm no expert, so I'm not sure if each test detects multiple potential metabolites or only the main one, but I know for a fact the oxycodone test looks for norbuprenorphine, which is also, coincidentally, a metabolite of nalaxone, and to a lesser degree buprenorphine. Which explains why Suboxone triggers a false positive for oxy (many people don't know this, but a clinical study performed back in 2009 confirmed over 70% of Suboxone patients tested a false positive for oxycodone. And both I and my brother can attest to it with first hand experience with the false positive.
