Automate script | Rename a defined list of filename by a defined list of word powershell

All my code:

    #read list filenames + filter#
    $listname = Get-ChildItem 'Y:\Users\H\Documents\D\Game Of Throne' -Filter *.bmp 

    #Read list file txt#
    $line = Get-Content 'Y:\Users\H\Documents\D\Game Of Throne\prod\recup.txt'

    #account name#
    $count_listname= $listname.count

    #account line txt#
    $count_line = $line.count




    #number of max action (inf_list)#
    $count= $count_listname, $count_line 
    $inf_list= ($count | measure -Min).Minimum 

    #Var file by file of folder#
    $list_split= $listname
    $list_split | foreach {
        $list_split = $_ -split '*'
        Write-Host $list_split []
    }

    #Var line by line of the textfile#
    $line_split = $line
    $line_split | foreach {
        $line_split = $_ -split '*'
        Write-Host $line_split []
    }
    #Select type to delete#
    $erase=Read-Host "Enter the type to delete"

    #Select number of line#
    $nb = Read-Host "Enter the number line to add."

    #Line of replace#
    $list_input[$nb] = Read-Host "Line(s):"

    #Boucle#

    $i= 0
    while ($i -le $nb-1) {
        $list_input[$i]| rename-item -newname { $_.name -replace ( $erase , $list_input[$nb] )}
        $i++
    }

    #output#
    echo "File folder" $listname ""
    echo "Fichier texte " $line ""
    echo "Number of file in folder" $count_listname ""
    echo "Number of line in txt" $count_line ""
    echo "Number max of actions" $inf_list ""
    echo "Line by line" $line_split ""
    echo "List one by one" $list_split ""
    echo "Type to delete" $erase ""

#echo table($line_split[n] or $line_split[n]#

I have some problems to automate the script (Read-Host) This is working with the $erase but i need it too for the number of table-line and then the lines (without a textfile)
