New guy's questions

Hello. I just start to use this tools. I know how to create a site map and run the scraper. Just wonder if I create many site maps, is there a command line to run all of them and get the csv file for all? Do I have to use the cloud service to do this?
Also, I am not able to scrape data for this site: https://coronavirus.1point3acres.com/en
Can anyone tell me if this site is scrapable or not?
Thanks!
