1. Dynamic microphones do not need a power supply (partially true)

The vast majority of dynamic microphones can manage without power but there are some exceptions. Basically, all condenser microphones need some kind of power supply. This is primarily to supply the impedance converter and for non-electret condensers to charge the electrodes (membrane and back electrode). Active dynamic microphones need a power supply as well.

2.Condenser microphones are louder than dynamic microphones (not true)

No, one microphone is not louder than another; it is just a question of sensitivity. In general, condenser microphones exhibit a higher sensitivity than dynamic microphones. Either way, the sensitivity should always be chosen relative to the requirements of the job. In other words, if the microphone has to handle very high sound pressure levels (SPL), it is best to select a unit with a low sensitivity – whether it is a condenser or a dynamic microphone.

3. It is easier to mike up the band using dynamic microphones (not true)

This statement is more related to tradition and laziness than it is related to fact. No matter what you choose, you have to consider the specs and the application.
In some cases it is argued that the frequency range or the opening angle is too wide. Well, sometimes it is actually easier to reduce bandwidth on a condenser than it is to equalize a dynamic microphone. In general, the directional characteristics of the condenser microphones are at least as good as can be achieved by any dynamic microphone. But, as always, it’s important to pick the right microphone for the job no matter what transducer it may have.

4. Condensers mics feed more easily than dynamics (not necessarily true)

As with many of the previous statements, this is simply a question of choosing the right microphone. One basic error often made is selecting a condenser microphone that is developed for recording at a distance. When amplified, this may result in low-frequency feed. Instead, use a low-cut/high-pass or pick a microphone that is designed for stage use.

5. Dynamic microphones can handle higher sound pressure levels than condenser microphones (not true)

Condensers can, in general, handle extremely high sound pressure levels. The question instead is whether the mike preamp can handle all the juice coming out of the microphone.

An extremely loud singer can produce a sound pressure peak level in the range of 150 dB, measured at the lips. If you have two microphones with a sensitivity of 1 mV and 10 mV respectively (what comes out of the microphone when exposed to a sound pressure level of 94 dB re 20 μPa), you have outputs of 0.63 and 6.3 volt peak! Signals of this magnitude should instead be handled by the line input or the signal should be attenuated in some way.
