I bought a domain name from google domains i.e abc.com
I want to create a new google workspace with a mail server which has all emails as xyz@abc.com, for creating this google is asking for a domain name (abc.com)
I also want to create a website "abc.com" Can I create both of the above i.e a mail server and website with same domain
Yes, you can create both. There should not be a problem. Many Google Workspace customers do the same.
