6. How many third parties?
Looking back at Yahoo they detail their 3rd party policies .htm
Analytics Partners
Social
Widgets
Advertising
Then my snipping tool ran out of batteries!!!

7. What Do They Do?
“These companies may collect information about other apps on your various devices”
“These providers can collect your information, including your IP address, page header information, browser information, and other information just as if you had visited their website”
“This information also includes the kind of content or ads served, viewed or clicked on; the frequency and duration of your activities; the sites or apps you used before accessing our Services and where you went next; whether you engaged with specific content or ads; and whether you went on to visit an advertiser's website, downloaded an advertiser’s app, purchased a product or service advertised, or took other actions.”
“In some cases, the third party may recognize you through its widgets even when you do not interact with the widget”
“These companies may collect information to deliver you customized ads”
