Answer 1

AFAICR the LinkToPrevious is not for the section, but for the individual headers/footers. But the HeadersFooters collection is an oddity anyway. I'm thinking in VBA here, not PowerShell, but I'm not sure even your line
$Doc.LastSection.HeadersFooters.Header.Add("abcd $count");
will work. Assuming $Doc.LastSection gives you a Word Section object, I think you need something more like the following, suitably adjusted for PowerShell
$Doc.LastSection.Headers(wdHeaderFooterPrimary).Range.Text = "abcd $count"
$Doc.AddSection()
$Doc.LastSection.Headers(wdHeaderFooterPrimary).LinkToPrevious = $false;
