Answer

$MainDir = "\path_to_folder\MainFolder"
$NameToFind = "S\d\d\d\d\d"
$initialList = 'EQ', 'kk', 'pp'
$fileRecord = "she-is-so-smart"

function MainScript {
    Write-Output "Start Script"
    $today = Get-Date -Format "yyyy-MM-dd"
    if ($MainDir -notmatch '/$') {
        $MainDir = "$MainDir/"
    }
    $mainDirs = Get-ChildItem -Path $MainDir -Directory
    $fileListResult = New-Object Collections.Generic.List[String]
    $folderCountList = New-Object Collections.Generic.List[String]
    
    foreach ($initial in $initialList) {
        $subDirsName = Get-ChildItem "C:\Users\S\Documents\MainFolder" -Recurse | Where-Object {  ($_.Name -match "$NameToFind.*$initial$")}
        $nameFolders = $subDirsName.Parent
        $nameCount = ($subDirsName | Measure).Count
        $countResult = "User: $initial, has: $nameCount folders done."
        Write-Output $countResult
        
        
        $folderCountList.Add($countResult)
        

        $fileListResult.Add("`nFolders done by: $initial")
        foreach ($file in $subDirsName) {
            $fullName = $file.FullName
            $fileListResult.Add("Name: $fullName")
        }
    }

    $fileRecordName = "$fileRecord`_$today.txt"
    $fileRecordPath = "$PSScriptRoot\$fileRecordName"
    $folderCountList | Out-File -FilePath "$fileRecordPath"
    $fileListResult | Out-File -FilePath "$fileRecordPath"  -Append

    Write-Output "Saved results to $fileRecordName"
    Write-Output "End Script"
    read-host “Press ENTER to exit...”
}
