Yes for this issue this information is sufficient, and 16GB is less for the
configuration you are trying to deploy. As Phil said with 16 GB swap your
installation might complete but better would be to go with more RAM then
swap as with swap it will be slow.

Yes, this could also be related to configuration, so suggest you try after
updating RAM. You checked at which task it was stuck?

Re installation of CentOS on your baremetal machine is not needed(But if
you try to deploy master ensure you have CentOS8 installed as base OS, for
train or older you can go with CentOS7).
quickstart will take care of cleanup of deployment when doing redeployment.
Just ensure you cleanup the workspace(default is ~/.quickstart, rm -rf
~/.quickstart) or use --clean with quickstart.sh. You can also check out
phased installation[1].
