can the info in the user's profil pages be asked while registering?

Hello, I want to ask more question while registering. I tried many plugins but none of them are fit my needs.
Actually I like the registration form of WordPress. I want to add the questions in users profile information while registering. I mean, I want to include name, surname, e-mail.. fields. So when I look at the users’ profile, I want to see those information because they filled them while registering.
I don’t know writing php codes. So I want to ask someone who knows it well. I see some codes in wp-login.php like:

<label for=”user_email”><?php _e(‘E-mail’) ?>
<input type=”email” name=”user_email” id=”user_email” class=”input” value=”<?php echo esc_attr(stripslashes($user_email)); ?>” size=”25″ tabindex=”20″ /></label>
</p>

How can I write a code to have name and surname and occupation information of the visitors?
