Just check username_echo variable is set or not

<div id="signup">

       <h1>Sign Up</h1>
       <h4><?php if(isset($username_echo) && !empty($username_echo)) echo $username_echo;?></h4>
       <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
          <div class="top-row">
             <div class="field-wrap"> <label> First Name<span class="req">*</span> </label> <input type="text" required autocomplete="on" name="first_name"/> </div>
             <div class="field-wrap"> <label> Last Name<span class="req">*</span> </label> <input type="text"required autocomplete="on" name="last_name"/> </div>
          </div>
          <div class="field-wrap"> <label> Email Address<span class="req">*</span> </label> <input type="email"required autocomplete="on" name="email"/> <?php echo $email_echo //display some PHP here?> </div>
          <div class="field-wrap"> <label> Username<span class="req">*</span> </label> <input type="text" required autocomplete="on" name="username"/> </div>
          <div class="field-wrap"> <label> Set A Password<span class="req">*</span> </label> <input type="password"required autocomplete="off" name="password"/> </div>
          <button type="submit" class="button button-block" value="sign_up" name="sign_up"/>Register</button> 
       </form>
    </div>
