1) There is a red lined square on the file LVL2.
As you see this part got bigger on the file LVL3.
How can I do that on a PDF?
2) I also cropped and saved those red lined squares as JPEG files.
How can I import those and make a pdf like I want and put page numbers?

Are you asking how to Draw a RED Square, increase margins and add automatic page numbering?
I think the question is about impositioning, i.e. cropping and scaling a PDF.
Most impositioning tools can manage that, I would suggest jPDFtweak.
http://jpdftweak.sourceforge.net/
Though I am not sure if it can add the page numbers...
If you want a more manual approach you could of course split the PDF into one cropped PDF per page, and import those pages manually into image frames in Scribus.
Or write a script for it.
My question is about scaling.
Can I scale the pdf with Scribus or any software you suggest?
(So I don't want to deal with that cropping, converting, pasting one by one.)
I repeat:

I loaded pdf file into the software you suggested.
Now how to do what I want?
this could be a job for GIMP, open .pdf in GIMP, Crop/Enlarge/draw red box/save
Where is GIMP on jPDF Tweak Software?
I couldn't find that?
try gimp.org
What should I do on this software?

Tell the software to do what you want. I did not say it was trivial.
Did you read the manual?
http://jpdftweak.sourceforge.net/manual/index.html
It is probably the Shuffle/N-up tab that you want to use. Load one of the presets first to try to understand how it works.
Here is a more complex example:

I would not recommend using GIMP for this, because GIMP will rasterize the pages.
