Linux uses memory very efficiently, so if you have 32GB of RAM, you are in great shape for most applications. Linux will allocate to active processes and deallocate memory to idle processes as required.
To use "less RAM" as you ask, you need to manage the running processes.
Best is to look at the memory allocated "per process" and not only the "free memory" stats you posted.
Hope this helps.
