Create Deep Link 301 Redirects for my site

I have taken a Godaddy-created website and redirected it to a Wordpress website with new content but similar pages. I redirected the URL through Godaddy hosting to the new URL, but none of the internal pages of the old site are redirected to the similar pages of the new site. I tried adding some code to the .htaccess file of the old site but it isn't working (I don't know what I am doing!) I need someone to set up these 301 redirects for me. The code for the new pages is already sitting in the .htaccess file so you can see where I want the old pages to go. I will provide access to the old and new site platforms and hosting accounts and anything else you need.
