Bi-amp: it essentially has 2 power amp sections in it. One used for the high and mid frequencies, and another one for low frequencies. To use an amp this way requires 2 speaker cabinets.

Bridged: An amp with 2 power amp sections that are capable to be combined into one output to one cab. The amp MUST be made to be able to run this way. Not all amps of this design are capable of being bridged. When bridged, you are combining the power of the 2 sections, thus it will have a much higher power rating.

Power Amp: The final amplifying stage in an amplifier, can also be a seperate unit. This is where your output power comes from and goes to the speakers.

Pre Amp: Can be a seperate unit or combined in one unit with a power amp. The pre-amp has the tone circuitry in it. It takes the weak signal from the bass and amplifies it to a level that is useable by the power amp. If you have a stand alone pre-amp, you won't be able to hook it directly to a speaker. It requires a power amp.
