It will be custom work. You can add this code snippet in your child theme’s functions.php to achieve this:

add_filter('bp_core_signup_send_validation_email_message','ps_user_data_to_email',10,2);
function ps_user_data_to_email( $msg, $user_id )
{
  $user = get_user_by( 'id', $user_id );
  if(!empty($user))
    $data1 =  xprofile_get_field_data('your_first_field_name',$user->ID);
    echo 'Your Profile Field Name'. ' : '.$data1;
    $data2 =  xprofile_get_field_data('your_second_field_name',$user->ID);
    echo 'Your Profile Field Name'. ' : '.$data2;
}

You can do this for all the profile fields by just repeating the code to get data3 data4 like I did for data1 data2 and obviously you have to use your profile fields name in place of ‘your_first_field_name’, ‘your_second_field_name’ and ‘Your Profile Field Name’.
