Perhaps you are thinking of countries that were formerly French colonies.
If so, it's impossible to definitively say there are only 4. There are dozens of independent nations across the globe that were once under French colonial rule.
Some prominent examples include:
* Algeria
* Senegal
* Morocco
* Tunisia
* Vietnam
* Cambodia
* Laos
* Haiti
* Canada (partially)
Could you please provide more context or clarify what you mean by "4 counties"? I can then offer you a more accurate response.
