ErrorDocument 404 /index.php?key=404
RewriteEngine On

RewriteCond %{HTTP_HOST} !^humor\.mysite\.ru$
RewriteRule .* http://humor.mysite.ru%{REQUEST_URI} [R=301,L]

And i have google confirm file for webmasters, so when i add file at my root directory and try to see what inside throw the browser - server redirect me to index.php, but it should show me these file

Order of rules matters. Your very last line will NEVER get "executed" because previous rule will redirect all .html files to index.php.

Try these lines (you can safely delete the very last line for contest.html):

# Default
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-zA-Z_0-9\-]+)\.html$ index.php?key=$1 [L]

Alternatively, add these lines after domain redirect rules and before # Index Page block

# Do not do anything for already existing files or folders
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .+ - [L]
