Loop for downloading files with url of websites

Hello to All,
I have an already working code to open files in my own pc.
When I modify this code to download a list of files from web, it gives me various errors.
There are urls on column A. And new names I give them are on column B.
I want to save and rename bunch of csv files with one click, The same code could open files from a directory.
I have modified it to open urls. But I could not manage it work. It might seem a bit confusing but I left it intentionally this way so may be some might see the point I make mistake(s)

Thanks in advance to whomever honours my question with their replies.
