Turboprop engines

I noticed that many aircraft have a turboprop engine and I don't know anything about flying them. I know only how they work in theory. So:
1. How do I start this engine? Beside pressing CTRL+E?
2. I know that I first have to engage the engine start buttons, when I do that I hear some sound but the propeller is not turning. What is that sound? The turbine? If that's the sound of the turbine how come the propeller is not turning with it?
3. How do those jet engines (turbojet, turbofan and turboprop) start working? I don't mean on buttons now, I mean on the starting system. How does it work?
4. What's the condition lever for? And how do I fly with it? Do I have to change it's settings during takeoff, climb, cruise, descent and landing?
5. In turbojet and turbofan engines the air is blown out trough the exhaust and that pushes the aircraft forward. But where does the air go in a turboprop engine?
