All of the numbers that you listed are Germanium transistors, which were the most common types when transistors were first introduced. Modern transistors are Silicon types. The two types can be interchanged, but the circuits will need to be altered to allow for the different biasing needs.
Transistors can be thought of as similar to tube triodes. The Collector would be the plate, the Emitter the cathode and the Base the input grid. In most circuits the power supply will connect to the Collector, the Emitter will connect to ground either with or without a resistor and bypass cap and the signal will be applied to the Base. In most cases the base will need to be biased on with resistors.
And just like tube stages the signal from the collector is 180 degrees out of phase from the input and in phase at the emitter.
