How can override pricedifference.phtm into my custom module in app\code\vendor_module or add new block after exact this block?

Answer 1

To add a new block after product.info.pricedifference block.

In catalog_product_view.xml in your module add

<referenceContainer name="product.info.left">
    <block class="Vendor\Module\Block\FileName" 
           name="product.info.custom" 
           after="product.info.pricedifference"
           template="Vendor_Module::custom.phtml">
    </block>
</referenceContainer>
