but pages are satisfy this condition only
RewriteRule ^/product-* /product/index.php?cat=$1 [L]
what doing wrong in my code.
Please help me and thanks in advance

Answer 1

It is unclear what exactly you want to achieve, but we can make two suggestions...
By the way... ^/product-* is not the regular expression you want. We have to assume you don't really know how regular expressions are build. I suggest you start reading about them. They are a very important and mighty tool for a developer when having to deal with simple text analyzing tasks.
Here are two suggestions for working internal rewritings (you did not implement any external redirections at all yourself):
A plain internal rewriting as you asked in the question you wrote:
RewriteEngine on
RewriteRule ^/?product-india/?$ /product-india/index.php [END]
RewriteRule ^/?product-us/?$ /product-us/index.php [END]
RewriteRule ^/?product-\w*/?$ /product/index.php [END]
Another one handing the "country" over as category argument:
RewriteEngine on
RewriteRule ^/?product-india/?$ /product-india/index.php [END]
RewriteRule ^/?product-us/?$ /product-us/index.php [END]
RewriteRule ^/?product-(\w+)/?$ /product/index.php?cat=$1 [END]
In case you receive a http status 500 using those rules ("internal server error"), chances are that you operate a very old version of the apache http server. In that case replace the [END] flags with the old [L] flag, most likely that will work equally fine here, though that depends on your specific setup.
The above rule sets will work likewise in the real http servers host configurations and in dynamic configuration files.
And a general hint on that: you should always prefer to place such rules inside the http servers (virtual) host configuration instead of using dynamic configuration files (.htaccess style files). Those files are notoriously error prone, hard to debug and they really slow down the server. They are only supported as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).

Answer 2

You can have your rules as this in site root .htaccess:
RewriteEngine On
# if <uri>/index.php exists then use it
RewriteCond %{DOCUMENT_ROOT}/$1/index..php -f
RewriteRule ^([\w-]+)/?$ $1/index.php [L]
# otherwise use product/index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(product-\w+)/?$ product/index.php?cat=$1 [L,QSA"NC]
