Output

[skullo]

I wanted to ask whether if I want to produce output is another example like the motor circuit where I have to make a connection to the RFID circuit, whether at the LED or buzzer? or where?

What output? All connect to PIC.

can or not RFID circuit combine with another circuit?

You can interface RFID Reader into PIC. Then, other I/O PIC, you can connect to many other device. See example RFID.

Not really clear what are you asking about.

You are asking to integrate a RFID circuit with another circuit, like bare board? Or you are referring to integrate RFID reader with another circuit? Shahrul have show you a good example. Or you are asking whether you can modify Cytron DIY RFID project to do other stuff?

Clearly.... you are not familiar with microcontroller

Study more and do some simple project such as LED blinking with some switches....
