What are all actions do I need to perform to get the free coins?
As said earlier, it varies from a crypto project to project. Some will simply ask you to join their telegram channel or register on their site, some will ask you to follow and retweet their one of the post, or post on your Facebook wall. Some projects will also ask to post on forums such as BitcoinTalk or even write a Blog Post about them. BitcoinTalk is one of the oldest and most active forum to discuss Bitcoin & crypto projects. We will recommend you to signup for BitCoinTalk forum if you want to stay ahead of the game.
