Is there a way where I can take a number as argument and then create that number of groups of the same thing?

I need to deploy N number of robots and want N to be a roslaunch argument.

Not sure what's your specific need.

Maybe this is enough if you want to run something like roslaunch my_file.launch robot_num:=N

But how do I write it in the launch file that the group that specifies the spawning of robot models shoudl be there N times too?

I think it'll be easier to use shell script. For example, you can use for...do...done in shell script to launch your launch file with different robot_num, then you can change the namespace of group of nodes each time by using arg in launch file.
