What are the Types of Op-Amps ?
Broadly its categorized as BJT based op-amp, FET(JFET and MOSFET) based op-amps. Except this these are also categorized according to frequency range, power consumption and operating voltage range.

What are the other types of FET ?
HEMT, MESFET, MODFET, NOMFET, OFET, DEPFET, CNTFET, … see the page on FET on Wikipedia.
What is IGBT ?
Insulated Gate Bipolar Transistor. It is a device for power control. It has a structure akin to a MOSFET coupled with a bipolar-like main conduction channel. These are commonly used for the 200-3000 V drain-to-source voltage range of operation. Power MOSFETs are still the device of choice for drain-to-source voltages of 1 to 200 V.
