Since one had failed and your car has clocked about 95000kms which is quite high for a change, it is ideal to have all the four injectors changed as this will ensure that there wont be any failure of fuel injection or poor performance for a long time. If not the others may follow suit in due course of time and so changing all FOUR is recommended.

You don't. You just crank the engine until it starts. Modern vehicles work on a pressurised system with a return back to the tank. The fuel is pumped from the tank to the injectors and excess fuel is returned to the tank.
The good news is that you have power and your starter is working. If you can't get it started, and had rough idle before that, there are a couple of high likelihood directions to go, so lets start with the least painful.
For proper ignition, you need three things - air, spark, and fuel. If you get the wrong mix, rough running or none. Since you went from running rough to not turning over, you are likely being choked off from one of the vital three (An engaging starter is also needed, but it sounds like you have that)
Not enough air would most likely be a dirty or clogged air filter. There are lots of Youtube videos on how to access and change the filter, such as ( How to change engine air filter on Audi A6 C6 4F 2 0 tdi ). I don't know if it's exactly the same on model, but it's likely pretty close. An auto parts store will be able to guide you to the specific replacement filter if it turns out to be in need of replacement. If you're stranded and not near an auto parts store, you can at least examine the filter and gently bang it out against a solid surface to dislodge overt dust bunnies (try not to breathe any of this, do it outside if you take this route). Also take a look at what's up with the filter. If it's just dust, it may have been overdue for replacement. Oil or other viscous liquid could be signs of more serious problems like an oil leak.
Lack of fuel would come from an old, clogged fuel filter, or clogged fuel injectors. Similarly, videos like this ( Fuel Filter Replacement Audi A6 ) can guide you on the filter, and ( How to Change an A6 Injector eHow ) or the like can guide you on fuel injectors. Try the filter first, less pain. Then if you can get it started, get a bottle of fuel injector cleaner, add it to fuel tank while topping off your fuel with fresh new fuel (in case you got some bad gas), and see if performance picks up over then next 50 miles or so.
Finally, lack of spark. When is the last time the spark plugs were replaced? Worn, corroded or fouled plugs will give you dismal performance. See ( How to change your Audi A4 A6 or A8 Spark plugs and Coils ) and similar for how to on that. eBay is a good place to shop for the plugs, at least for lower mark-up. The procedures will also let you examine the electrical connections for wear. There are also usually seals around the coil packs to keep water splash out of the engine. Make sure the seals aren't all turned to crumbly black gunk (this'd be a sign to replace the coils, or at leas the gaskets.
There are plenty of other things that could be the issue, but with the slow decline into rough running, the odds are pretty good that something in the above will get you running.
Good Luck. If this is helpful, clicking it as helpful will be appreciated.

Consult the Owner's Manual, or view the oil specifications on the fill cal or dipstick (usually the fill cap) located under the hood. Depending upon mileage you may not want to vary from manufacture specifications, or risk voiding your vehicle's warranty should any remain. The VW TDI's are typically high maintenance engines. I would strongly recommend staying with the manufacture's oil specifications, and do not overfill the oil in your vehicle.
tandard practice to change the oil on a clutch replacement. Was the replacemmiles it's covered, but it's not sounds like the gearbox oil need changing. You don't say how many miles it has done. Gear box oil is not usually changed in a clutch replacement. Did an Audi garage carry out the rlacement? It could be the cable needs adjusting to allow the clutch to have free movement
