No. That is an old myth. Only time removes the alcohol.
Alcohol is a depressant - coffee (or more precisely caffeine) is a stimulant. The caffeine counteracts the effects of the alcohol (BUT - doesn't remove it from your system !)
Time is the only way to remove alcohol from your system, as the liver metabolizes and eliminates alcohol at a constant rate of about 0.015% per hour. Drinking water, coffee, or other fluids, as well as eating food, can help you feel better but will not speed up the elimination of alcohol.
You can help your kidneys to flush your system of alcohol by drinking lots of fluids that do not contain alcohol. Coffee is good.
No, alcohol does not remove THC from your system. THC is metabolized by the liver separately, and its presence in your system is not affected by alcohol consumption.
No food or drink will remove alcohol from your body, only time will do this.

No. It usually takes one hour per drink to leave your system, so 5 drinks would take five hours to leave your system completely. Although the caffeine in the coffee may help you feel more alert, it will not lower your BAC.
Only TIME takes alcohol out of the system. Products MAY seem to make it quicker but sorry, only time. If you've drunk, don't do any of the things you shouldn't have. no matter what you have taken. This include coffee.
Urine- much of the alcohol you consume will be expelled when you go to the bathroom. To speed up the process, drink water. Water dilutes the alcohol concentration within you, but speeds up kidney function, causing you to urinate more, and thus remove more alcohol. Vomit- if you consumed too much alcohol, the fastest way to rid it from yourself is to vomit. This expels the alcohol before it can even be taken into your system, essentially "undoing" the drinking. This is not healthy, as stomach acids corrode the esophagus and teeth, not to mention that it is not fun. But it is the best way to remove alcohol soon after you drank it. Increased metabolism- the faster your body metabolizes, the quicker alcohol can be processed and removed. Do this by running, eating, and being active. Be careful though, as these activities may be hard and painful with all the poison running through your system. Time- this is the most 'truthful' answer. The above may help process alcohol in your system, but you must let your body take care of you. Take some time to relax. Sleep, watch tv or listen to music to pass the time. Be careful with sleep though, as you could continue to get sicker and not be able to get help. If you recently consumed alcohol, make sure to have a good friend watch over you who can help you as you need.
Coffee cannot "clear" urine - whatever you're trying to "clear" it from. It's not going to cure an infection and there are no magic potions that remove drugs from your system, so ... nope.
