List other applications you want to launch, one command per line. Note that there is no '&' at the end of every line since this is not a shell script. Don't append & at the end of any line. Since this is not a shell script, shell expansion like ~ or $HOME won't work. If you need this, write a script and do the shell things there, than list the script here in the autostart file. If a line starts with @, the program will be guarded by lxsession. That means: If the program crashes, it should be automatically restarted. If the program is terminated normally, or is terminated because it receives SIGTERM or SIGKILL, then the reload won't happen.
Another way to start programs on session startup is to add their *.desktop files in ~/.config/autostart. Please refer to the Autostart spec.
