I am running "roslaunch px4 multi_uav_mavros_sitl.launch" with iris model. It was running perfectly well until i edited the iris file and added the camera to it. A number of errors start coming as i run the launch file

Can you take a look at the log that it references here (hopefully it's not empty)? 

failed to start local process: /home/kavin/Firmware/build/px4_sitl_default/bin/px4 /home/kavin/Firmware/build/px4_sitl_default/etc -s etc/init.d-posix/rcS -i 1 -w sitl_iris_1 -d __name:=sitl_1 __log:=/home/kavin/.ros/log/cbc6fdd6-04a6-11ec-b1bc-0800279cdffe/uav1-sitl_1-6.log

Also it looks like you are launching mavros multiple times and that's why the previous instances of mavros are shutting down.
