I have assigned sh -c 'firefox & gnome-terminal & nautilus & google-chrome-stable & opera' in "Keyboard" in Xubuntu 14.04 to open multiple applications with a single shortcut.

Whenever I trigger my keyboard shortcut, all of the programs open at the same time, which is what I was trying to do; but, I am concerned that even though my solution works, that using & instead of ; to run a set of commands unconditionally could be a bad idea, or at the very least, improper. To elaborate, I actually did try ; before I tried &, but it didn't work for some reason. && also did not work for what I was trying to do, because it would open gnome-terminal only after I closed Firefox, and so on.

I barely know what I'm doing here, as I am inexperienced with shell stuff, so if someone more experienced could chip in and let me know whether or not my command is a good and viable solution for what I'm trying to do, it would be much appreciated.

Command lists and background invocation is actually the right shell feature to do here. If the shell script works for you there are no considerable drawbacks in this context.
