firstly i will like to know how i can download my website or save it to my device. so that i can upload it incase i want to creat a new website.
You can login to File Manager and download pieces of your website, or you can use a FTP client, such as FileZilla to download your entire website more easily.
secondly, i created a new website and will like to move the data of my previous website to the new one.
Just use FileZilla to upload the data to your new website
thirdly please how can i change the link of my website
Once you've created a website, you can't change it's link. You can only park/point a domain to it, or you can use a free subdomain to link to your website. You should go to: cPanel > Set web address > Add address > Free subdomain
in brief i created a sample website called reliable pet courier and i want to change the name to efficient pet carrier please how can i do it ??
You can't change the website's name once you've already created it, but you can assign a free subdomain to it, which you've already done
or how can i move my old reliable pet courier to my new efficient pet carrier
You can create a new website and move the entire content from the old website to the new one, just created.
also please how can i download my website data that is from the file manager so that i can upload it if need be.
