Apply several conditions when uploading an avatar image

I had a problem when uploading the avatar image, which I fixed: link

Now I want some conditions to apply when uploading an avatar image, In the one user avatar plugin settings, I ticked the avatar image size change and set its size to 32×32.

1. Only allow uploading avatar images that are equal in width and length, exp : 300×300, 1000×1000
2. When the avatar image is uploaded, it will remove the original size and replace it with a scaled 32×32 size. I want to keep the original size, actually the avatar image has 2 sizes : original and 32×32
3. When the avatar image is changed, all 2 sizes are removed and the avatar image is replaced with the original 2 sizes and 32×32.

This is my code :

function customize_wpua_action_process_option_update( $user_id ) {

    global  $blog_id,
            $post,
            $wpdb,
            $wp_user_avatar,
            $wpua_force_file_uploader,
            $wpua_resize_crop,
            $wpua_resize_h,
            $wpua_resize_upload,
            $wpua_resize_w,
            $wpua_admin;

    // Check if user has publish_posts capability
    if ( $wp_user_avatar->wpua_is_author_or_above() && ! $wpua_force_file_uploader ) {
        $wpua_id = isset( $_POST['wp-user-avatar'] ) ? absint( $_POST['wp-user-avatar'] ) : 0;

        // Remove old attachment postmeta
        delete_metadata( 'post', null, '_wp_attachment_wp_user_avatar', $user_id, true );

        // Create new attachment postmeta
        add_post_meta( $wpua_id, '_wp_attachment_wp_user_avatar', $user_id );

        // Update usermeta
        update_user_meta( $user_id, $wpdb->get_blog_prefix( $blog_id ) . 'user_avatar', $wpua_id );
    } else {
        // Remove attachment info if avatar is blank
        if ( isset( $_POST['wp-user-avatar'] ) && empty( $_POST['wp-user-avatar'] ) ) {
            // Delete other uploads by user
            $q = array(
