What are their differences:

$ git branch -a
* main
remotes/origin/HEAD -> origin/main
remotes/origin/main
What are their differences:
remotes/origin/HEAD
origin/main
remotes/origin/main
The remotes/origin/HEAD is the branch currently checked out in the origin repository, which means if you clone that repository, by default that branch will be checked out first.
The origin/main is a remote branch (which is a local copy of the branch named main on the remote named origin)
The remotes/origin/main, usually referred to as origin/main, is the location of a branch called main on the remote called origin the last time you did a git command. If they're related, main will have origin/main as its upstream.
Look at this question too: master vs. origin/master vs. remotes/origin/master
