Answer 1

You can access "Content Types" option in "Site Settings" page, identify the content type with that column and modify it manually. It will be replicated across all lists.

Answer 2

If you want to rename the site column in Content Type, we can use PowerShell below to achieve it.

$SiteURL = "http://test"
$OldColumnName ="Target Folder"
$NewColumnName ="New Target Folder"

$site = Get-SPSite $SiteURL
foreach ($web in $site.AllWebs) {

    $field=$web.Fields[$OldColumnName]
    if($field){      
        $field.Title=$NewColumnName
        $field.update()
    }   
    $web.Dispose()
}
$site.Dispose()
