Answer 1

You will wait a long time for an answer to such a question, smoke mana

Answer 2

Let's break it down point by point

RewriteEngine On
 RewriteBase /
тут все понятно

RewriteCond %{HTTP_HOST} ^www\.site\.ru$ [NC]
 RewriteRule ^(.*)$ site.ru/$1 [R=301,L]

here's the kicker. 2 errors are already starting, although not critical
This will be considered a redirect to without www let's not worry, I'll give you a redirect that will work without specifying a domain and looking less miserable.

RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]     
       RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*(default|index|main)\.(html|php|htm)\ HTTP/ [NC]
 RewriteRule ^(([^/]+/)*)(default|main|index)\.(html|php|htm)$ site.ru/$1 [L,R=301]

It looks like complete crap, what exactly were you trying to do with it?

RewriteCond %{QUERY_STRING} ^.+$
 RewriteCond %{REQUEST_URI} ^/$
 RewriteRule ^(.*)$ site.ru/? [R=301,L]

As far as I understand, this is again a miserable continuation of a self-written CNC in addition to ? at the end
, write down what exactly in your opinion each block does, we will bring to life the existing ... mmm how to say "structure"
And then we will think what was wrong.
