Hey I am wondering I can plug a speaker in as well as the receiver at the same time, I am looking forward to build a alarm with this. They both use the GND portt
I think people are waiting for you to post relevant information. Have you read the "how to post to this forum"
sticky thread(s)?
It's an interesting question. But before answering I'd like to know what speaker, what receiver and what are you thinking of plugging them into? Oh and what is a "GND portt"?
Steve
Please answer the question about the speaker and where you would like to plug it into.

GND is just part of the power supply. I don't think I've ever encountered something that did not connect to GND. You're also not limited to the GND pins on your Arduino, whatever type you have, as they're all the same and can happily be split to have more.
Power supply as such may or may not be able to come from your Arduino. Depends on what you're trying to power, really. A speaker normally requires an amplifier.
The speaker I am mentioning is just a Buzzer like in alarm clocks. I don't need to use it as alarm, do I need an amp ?
Depends on the buzzer.
Try again and this time post links to EXACTLY what you are trying to use. What speaker/buzzer? What RF module? What Arduino are you connecting them to? What is going to power everything?
Your original question seems to be "Is it possible to connect an RF receiver and a buzzer to an Arduino at the same time". The answer is yes.

SEAPANDA2:
Rf module (433MHz) and the BuzzerThey both utilities the GND(aka ground port)
Not a port, its a pin, or more formally a node.
A port can be two things, either a set of 2 or more connections to a network in circuit analysis,
or a related group of GPIO pins on a microcontroller.
