Don't use the ambiguous, greedy, and promiscuous ".*" pattern when a more-specific pattern can be used.
Also, be aware that rule-processing in .htaccess is recursive -- mod_rewrite will be re-started after any rule is invoked. Therefore, your second rule will always be invoked -- either directly, or just after the first rule is invoked (and you will see "site=index.php" as the value passed into index.php as a result).
See also the subjects of regular-expressions "anchoring" and "character-escaping". There is a concise regex tutorial cited in our Apache Forum Charter, accessible through the link at the top of this page.
RewriteRule ^(.+)\.html$ index.php?site=$1 [L]
RewriteRule ^(([^/]+/)*[^./]+)$ index.php?site=test&name=$1 [L]
The second Rule's pattern matches "page URL-paths" with no periods in them and no trailing slashes, preceded by any number of subdirectory levels (including zero) which may contain periods. So example.com/foo->index.php?site=test&name=foo and example.com/foo.foo/bar->index.php?site=test&name=foo.foo/bar
You may not need the "allow and include subdirectory levels" or "allow periods in subdirectory paths" features, but I thought I'd might as well include them, as it's always easier to take away than to add...
