The traditional parallel port is a 25 "d-sub" connector.
Serial ports come in two flavors, either 25 pin "d-sub" or 9 pin.
USB (another serial communication standard) is a different animal.
PS/2 is also a serial port and it has six pins.
A common serial port has either nine pins (by far the most common) or sometimes on very old equipment 25 pins. It turns out that they are completely compatible with a very simple adapter... the older standard just used a wider connector.
The nine pins are arranged in two offset rows. The port (on a computer) is "male" in that the metal pins are sticking out, with a metal shield around it forming a trapezoid with slightly rounded corners.
A typical serial port has 9 pins. also known as DB-9 male.

It's called a COM port.
If it has 15 pins it is NOT a serial port! A serial port will have either 9 pins (DB-9), or 25 pins (DB-25). The 15 pin connector (usually blue) is analog video or VGA, and yes if your graphics card is powerful enough it can run dual monitors. You can either buy a dual port graphics card or a splitter to run dual monitors
