Edit the post title from the frontend

Question

I have this form that allows-me to change some things of the current post in my frontend:

<form id="featured_upload" name="featured_upload" method="post" action="#" enctype="multipart/form-data">
<p><span class="badge badge-primary"><input type="file" name="my_image_upload" id="my_image_upload" multiple="false" required /></span></p>
<p><input type="text" name="newtags" id="newtags" value="" placeholder="new tags aqui..." /> <input type="text" name="h2" id="h2" value="" placeholder="h2 heading aqui..." /></p>
<p><input type="hidden" name="post_id" id="post_id" value="" /></p>
<?php wp_nonce_field( 'my_image_upload', 'my_image_upload_nonce' ); ?>
<span class="badge badge-light" ><input id="" name="" type="submit" value="Upload"/></span>
</form>  

Starting the saving process...

// Check the nonce is valid, and the user can edit this post.
if ( isset( $_POST['my_image_upload_nonce'], $_POST['post_id'] ) 
    && wp_verify_nonce( $_POST['my_image_upload_nonce'], 'my_image_upload' )
    && current_user_can( 'manage_options', $_POST['post_id'] )) {

What I would like to do is to have the habitability of changing the post title (and slug also, of course...).

Can this be implemented on this form?

Yes, you can change post title and slug from frontend. by using wp_update_post you can change title and slug of post. in below code, it will update post title and slug of post_id. Replace your-post-title-field with your title field in form. slug will generated using that post title.

if ( isset( $_POST['my_image_upload_nonce'], $_POST['post_id'] ) 
    && wp_verify_nonce( $_POST['my_image_upload_nonce'], 'my_image_upload' )
    && current_user_can( 'manage_options', $_POST['post_id'] )) {

    if(!empty($_POST['your-post-title-field']))
    {
      $new_slug = $new_title = sanitize_title($_POST['your-post-title-field']);
        wp_update_post(
            array (
                'ID'        => $_POST['post_id'],
                'post_title' => $new_title,
                'post_name' => $new_slug
            )
        );
    }
}
