Disk Utility with extra Mac HD after clean install on Monterey (formerly Big Sur)

Not sure if I need to re-format and re-install again. Is it normal to see so many Mac HD, and should I try to remove the extra ones? Had some HD issue where somehow there was no space left and thus there was nothing to do but to clean install everything. Now it seems there are multiple Mac HD / Mac HD - Data, with different avail space, as shown:
