You need an ohmmeter or multimeter (set in resistance measurement mode). Choose the 1kOhm range. Connect the meter's wires (red & black) each to the diode's terminals, then switch the terminals. In one case you should see a meter reading that is substantially lower than the other. If that is not the case (both read high or both read low), the diode is probably faulty.
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
Yes you can. The UF is a significantly faster diode. The peak forward surge current is 50 amps less, but apart from that they have much the same characteristics.
It depends on how the diode is damaged. There are generally two cases. One, the diode is shorted, and conducts with a low impedance in both directions. The other, the diode is open, and does not conduct, having a high impedance, in both directions. The effect depends on the particular circuit. In a power supply, a shorted diode will often blow the fuse, while an open diode will result in no output, or in high ripple voltage output. Is it possible that diode has normal voltage output but wrong current,meaning low mA?
It is depend on your requirement .suppose you need a voltage regulator of 5V than you need 5V Zener diode.

The circuit symbol is like a diode, but with short lines coming out of each side of the cathode line, in opposite directions. To find breakdown voltage, find the part code and look it up.
