Answer 1

An alternative approach is below if your headers are always present in the file. It doesn't matter what the delimiter is as long as it isn't a number. Your delimited data in the sample is not consistent. Otherwise, Import-Csv would be a safer option.
$fileData = Get-Content file.csv
$output = for ($i = 1; $i -lt $fileData.count; $i++) {
"SET NUMBER{0}={1}" -f $i,($fileData[$i] -replace "(?<=^\d+).*")
}
$output | Out-File file.cmd
Explanation:
The format operator (-f) is used to help construct the output strings. The ID numbers are selected using regex by replacing everything that comes after the beginning digits on each line.

Try this:
# set current directory to script directory
Set-Location $PSScriptRoot
# import csv-file, delimiter = space
$content = Import-Csv 'test.csv' -Delimiter ' '
$output = ''
# create output lines
for( $i = 1; $i -le $content.Count; $i++ ) {
$output += 'SET NUMBER' + $i.ToString() + '=' + $content[$i-1].ID.ToString() + [environment]::NewLine
}
# output to file
$output | Out-File 'result.bat' -Force
