 Get companies block (on home, search or item page)

You can start with creating link in your header:
<a href="<?php if(function_exists('bpr_companies_url')) { echo bpr_companies_url(); } ?>"><?php _e('Companies', 'theme_name'); ?></a>
Anyway all those functions are optional and you may or may not use them, it has nothing to do with theme functionality, it is just for customization purpose (if you will read instructions carefuly).

i want to show bussiness profile some more places like seach page ect

If you mean adding links, you have all required functions above

i mean when some one seach on home page like other listings the bussiness profile should be show there too in listing above or below

I am not aware of such features.
Can you highlight to which part of product description is this related?
