Hey there well i'm trying to send a constant like 5 to arduino using simulink " to instrument " block and in arduino i have generated a model using "serial recieve" and a "gain" plus a "serial transmit" block and in my laptop i have the "query instrument" block but the thing i get is very weird .

I hope that you might have figured out by now. In case you haven't, try this:
The problem here is due to the fact that Arduino is sending the ASCII code and Query Instument is reading the binary values. You can change this at the Query block. Double click to open Block Parameters. Under the Query tab, set the data format as ASCII. You may also the set the ASCII format string as '%d', '%f', or '%s' based on the type of data you are sending.

To confirm, you are trying to send to more than 4 arduino simultaneously in one model ?

Yes as a part of HIL simulation each arduino is going to represent a sensor
