In this code I can see on the screen a group of seven sine waves moving, also on the right side I see a group of four random numbers(thanks to @Bartlomiej Lewandowski). My problem is that the numbers are blinking, I only need that those numbers stand still while the sine waves are moving. Then my formal question is How do I make the numbers stand still on this code?

So what you were doing was essentially trying to draw something to the surface and then fill it, however you have to draw everything in the proper order so What I did is I changed the position of the for loop drawing all of the text to the screen as this still draws it, but should get rid of the weird blinking/flashing that you were experiencing.
