You store the data in a array variable from the_post() query. You will get the array length and you can use looping such as for loop or while loop. Example:

for ($i=0; $i < $array_length ; $i++) { 
  if ($i == 1){
    //Here you can write the form block
  }
  else{
    //continue to write the post block
  }
}
