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.

NAME
services.window - file containing applications and their associated memory window ID
DESCRIPTION
The file is used by applications using memory windows.
Each line in the file associates an application with a memory window ID. A line in the file cannot start with a space or tab. The format
is a unique name, defining the application, followed by a space/tab, followed by a unique window_id. See the sample file in
Memory windows allows for the starting of a process in a unique or existing memory window where it can create and share objects with other
applications in the same memory window.
The creation of memory windows removes the system wide restriction on shared resources. Without memory windows, 32-bit processes were lim-
ited to 1.75 gigabytes of shared resources. Each memory window allows for the definition of a unique 1 gigabyte quadrant and since multi-
ple memory windows can be defined in a system, the system total for shared resources can exceed the 1.75 gigabyte limitation for 32 bit
processes.
The definition of a memory window is only available for 32-bit processes.
The file provides a central place for memory window applications to associate their memory window IDs. In the event there are any colli-
sions, only a change in is necessary to select another memory window for the entire application. If is not used, and user applications
hard code window IDs in their startup scripts, collisions are not easily detected or easily fixed.
A memory window application uses the command getmemwindow(1M) to extract the application's window_id from the file, and then passes that ID
to the setmemwindow(1M).
Using the same window ID places applications in the same memory window.
