You can pass it as a parameter to the template that you are calling,
but there's no need to even do that. Instead of the for-each, do this:

  <xsl:apply-templates select="*"/>

And then you can use position() within the templates that match.
For example, instead of the xsl:copy-of, use

  <xsl:value-of select="position() -1"/>
