RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+?)/([^/]+)/?$ $1.php?name=$2&dd=([^&\s]+) [L,QSA]
# handle /htaccess/movie-name internally
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ single-page.php?name=$1&dd=([^&\s]+) [L,QSA]
internal url : http://localhost/htaccess/single-page.php?name=pune-site-list-pune&dd=xcxc

Replace your last rule by this rule:
# handle /htaccess/movie-name internally
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)/?$ single-page.php?name=$1&dd=$2 [L,QSA]
([^&\s]+) cannot be used in replacement as this this regex to capture values in RewriteCond.
