I don't know if I understand your questions properly, but I think that your question is: is it legal to serve direct download links of free APK apps to people through your own website? APK apps are copyright protected so even when they are free you will have to get permission from the owner of the app to distribute the APK file from your website. So no, it is not legal to have such a website.
Yes, you can share the free apps to people but make sure that app developer allows that or you can host your own apps then it will be legal to do that. It will also help that if you include privacy policy and some legal notes on your website. It will help to run this site legally.
