1. see hear this link good chapter
2. Only blue, green, yellow, red and white have any significance in railroading. Blue: used to indicate personnel are on, under or about standing rail equipment Green: Proceed Yellow: Approach (the next signal prepared to stop) Red: Stop White: As a signal aspect, it's usually an off-white (called "lunar white"), and is usually found in a yard, station or terminal environment The red, green and yellow are used in different combinations to expand the information a signal conveys to a train crew, and the only legitimate ones are found in the rulebook issued to employees.
3. Basically they are similar to your traffic lights, green go, naturally, yellow means prepared to stop at the next signal and red, stop. There are dozens of variations and that can change from company to company. blue means workemn are under or around railroad equipment and it must not be coupled into or moved without authority white on a signal mast can mean proceed at restricted speed or it can mean there are occupied camp cars on a track and must not be coupled to or moved I am not positive but i think the other colors you mention may be faded or hard to see colors of the basics, for example amber and yellow are probably the same signal seen from different angles or on different signal appliances. As I said, there are others that may be specific to individual railroads and territories.
4. It depends on where in the world you are; signaling system differ quite a lot from country to country. But there are a few common meanings: green is for 'go'/'proceed', red lights mean 'stop', amber/orange/yellow signal some kind of 'speed restriction' and/or 'prepare to stop' - often amber and green are combined in different patterns to signal different restrictions. White is often used for shunting signals and/or other special signals (e.g. manual permission to pass a defective/red signal. Violet/Blue is used in some countries for movements in e.g. yards and/or shunting. For some descriptions of different europeasn signal systems you might take a look at http://members.aon.at/sig/asr/ensiglinks.html
5. Everyone has it right except for one detail. To the best of my knowledge, yellow is not used in railroading. What most people refer to as yellow, is actually amber.
