Solved CAPTCHA only in the first post

Is it possible to set CAPTCHA only in the first or 2 first posts ?
If yes is it possible to choose the kind of CAPTCHA ?
I mean letters, numeric captcha,pictures,click to confirm that you are human,etc

yes, you can set it up on the kunena configuration, also you need to enable the joomla- recaptcha plugin.

Yes and no. It depends whether you use the Crypsis template or some other template.

Yes, Kunena uses Google reCAPTCHA. Yes, Crypsis uses the Joomla Captcha - ReCaptcha plugin settings to choose between version 1.0 or 2.0 of Google reCAPTCHA. If you use a "non-HMVC" template—Crypsis is the only HMVC template in existence—the answer is no. If you use a "non-HMVC" template you use the Kunena configuration settings irrespective of the Joomla Captcha - ReCaptcha plugin settings. No, after you have chosen the Kunena template you will use (remember, Google reCAPTCHA is the only CAPTCHA software that operates with Kunena) you cannot "choose" how the reCAPTCHA will be displayed except to refine the colour scheme a little.

The article Using CAPTCHA spam protection in Kunena contains more information.

Yes it's possible. Enter the number 2 here (Configuration -> Security).

I ment change the kind CAPTCHA not the number of the posts.
Thank you anyway.

You can only change the color and nothing else.
