What do they mean?
How can I profit of them?

These are global variables, created by the program you ran. Pressing the corresponding F-key will recall their value to the stack. Most likely these variables are lists containing several parameters (like {X, Y, Z} ).

You can safely delete these. When you run the program, it will create them again if they are no longer defined?

I suggest you read the manual for your machine. Most of these issues are covered with the (admittedly large) manuals.
