How can change 'in baseball' the batter caractere for female unstead male ?

Do you mean on the iScorecast? After you hit Play, click the little gear to bring up the Game Options screen. Make sure you select "Softball" as the Mode.

Do you mean on the team website? Use the URL http://iscoresoftball.com/yourteamname" onclick="window.open(this.href);return false;

If neither of the above, then please provide more info.

BUT EVEN IF IT'S A BASEBALL GAME UNSTEAD SOFTBALL GAME ?

Yes. Figures are male or female based on the game type. You can not select based on the player.
