The plugin is programmed to detect the current language of the blog, and only if the current language is bn_BD, bn_IN or any bn_XX, (i. e. Bengali), the date will be shown with Bengali alphabets, otherwise, the date will be shown in Latin alphabet.
To set language of your blog, edit the wp-config.php file. Add the following lines there:
define('DBCHARSET', 'utf8');
define('WPLANG', 'bnBD');
Yes, with hacking. Uncomment line no 181 of the plugin.
Place <?php bongabdo(); ?> where you want the Bangla Date to appear.
To show Bangla Unicode date, the current language of blog must be Bangla (bn_BD) or (bn_IN), (See above);
Yes, partially. I'm using it with qTranslate. (http://www.sajidmc.net) It outputs date in English if the current language is not Bangla. On later versions, I'll release a full gettext supported plugin.
No
