List all free application on google play
Basically no.
As +RyanConrad said there are far too many free apps, which change constantly, to be listed on a single page.  If there are ~600,000 apps and an html link to an app was around 150 characters, and each character is 8 bits, that's ~85 megs just to get the full listing.  I don't know for sure, but I don't think your web browser will like trying to render that page.
