Error in displaying different HTML page headers according to the categories clicked

may help you . You are not posting the category id to your Category page. and if you set it static id=2 then it is normal that you get the wrong title.
You have to dynamicaly create the link with the id in it
code :
echo '<h3><a href="category.php?id">'.$row['Categoryname'].'</a></h3>'.$row['Categorydescription'];
echo '<h3><a href="category.php?id='.$row['Categoryid'].'">'.$row['Categoryname'].'</a></h3>.$row['Categorydescription'];

should help you out The contactform.php has obviously not been created for your usage in index.php:
code :
<body>
<div id="container">
    <div id="header">
        ...
    </div>
    <?php
      include ('contactform.php')
    ?>

    <div id="content">
       ...
    </div>
</div>

</body>
</html>

this one helps. My client insists on having all categories and posts displayed on one page. Bad idea, I know, but I need to do it. , i think recursive function will help you. something like this
code :
function loadCategories($categories, $level) {
    foreach($categories as $category) {
        $children = get_terms("product-category", array(
            "parent"   => $category->term_id,
        ));
        $cat_class = "";
        $heading_tag = "";
        if ($level == 1) {
            $cat_class = "primary";
            $heading_tag = "h2 style='text-align:center;'";
        } elseif ($level == 2) {
            $cat_class = "secondary";
            $heading_tag = "h3";
        } else {
            $cat_class = "tertiary";
            $heading_tag = "h4";
        }
        echo "<section class='cat $cat_class'>";
        echo "<header>";
        echo "<$heading_tag>{$category->name}<button>Expand</button></$heading_tag>";
        if ($level == 1) {
            echo "<hr  class='short' />";
        }
        echo "</header>";
        if ($level > 1) {
            echo "<div class='expander'>";
        }
        if (count($children) == 0) {
            $posts = get_posts(array(
                "post_type" => "products",
                "tax_query" => array(
                    array(
                        "field"    => "term_id",
                        "taxonomy" => "product-category",
                        "terms"    => $category->term_id,
                )),
            ));
            foreach ($posts as $post) {
                if ($level < 2) {
                    $cat_class = "secondary";
                    $heading_tag = "h3";
                } else {
                    $cat_class = "tertiary";
                    $heading_tag = "h4";
                }
                echo "<section class='cat $cat_class'>";
                echo "<header><$heading_tag>{$post->post_title}<button>Expand</button></$heading_tag></header>";

Any of those help You can use react-meta-tags. It allows you to meta tags in a declarative way and in normal jsx format, which will be moved to head (Check server usage on the doc).
code :
import React from 'react';
import MetaTags from 'react-meta-tags';

class MyComponent extends React.Component {
  render() {
    return (
        <div class="wrapper">
          <MetaTags>
            <title>Page 1</title>
            <meta id="meta-description" name="description" content="Some description." />
            <meta id="og-title" property="og:title" content="MyApp" />
            <meta id="og-image" property="og:image" content="path/to/image.jpg" />
          </MetaTags>
          <div class="content"> Some Content </div>
        </div>
      )
  }
}
document.title ="Welcome | here is your page title to display"; 
document.getElementsByTagName("META")[2].content="Your description about the page or site here to set dynamically";
