I am trying to open start-tor-browser using command prompt but it does not work.

When you use the shell, it looks in a list of directories called the PATH, to locate commands you give it. Usually, the current directory is not in the PATH, so you need to explicitly tell the shell where to find the script. This can be done by prefixing the name with "./", since . is shorthand for the path to the current directory.

Your home directory is not in your path. The above command will work if run from your home directory.
You need to read up on the linux file system.
