Try this

<?php 
    $dataSheet = $this->helper('Magento\Catalog\Helper\Output')->productAttribute($_product, $_product->getDataSheet(), 'data_sheet'); 
    $healthSheet = $this->helper('Magento\Catalog\Helper\Output')->productAttribute($_product, $_product->getHealthSheet(), 'health_sheet'); 
    if(isset($dataSheet) || isset($healthSheet)){
        //display your DIV
    }
?>

You can get the value of custom attribute using following:

$attribute = $_product->getResource()->getAttribute('custom_attribute_code');
if ($attribute) {
    echo $attribute_value = $attribute->getFrontend()->getValue($_product);
}

Magento – How to display an attribute on product view page in magento 2

In Magento 2, the price is placed on the product view page via a XML file named catalog_product_view.xml

You can view it in the catalog module's layout folder:

app/code/Magento/Catalog/view/frontend/layout/catalog_product_view.xml

Or if you installed Magento 2 with Composer:

vendor/magento/module-catalog/view/frontend/layout/catalog_product_view.xml

A container named product.info.price is created on the product view page. In the container, a block named product.price.final is created.

You can move the block with the <move> method in XML (Move Instructions):

<move element="product.price.final" destination="content" before="-" />

You can also create another block that uses the same class & arguments:

<block class="Magento\Catalog\Pricing\Render" name="product.price.final.copy" after="product.info.sku">
    <arguments>
        <argument name="price_render" xsi:type="string">product.price.render.default</argument>
        <argument name="price_type_code" xsi:type="string">final_price</argument>
        <argument name="zone" xsi:type="string">item_view</argument>
    </arguments>
</block>

*The above snippet is derived from what is in the catalog_product_view.xml file.

I hope this points you in the right direction!
