Each Familiar type requires a different kind of Biscuit to be tamed, and you can only get 1★, 2★, and 3★ Familiars through taming. But for a tl;dr answer: You can tame Familiars by approaching Brighterflies anywhere on the World Map, interacting with them, and then feeding them Biscuits.
How To Tame Familiars (Step-By-Step)
If you have enough Biscuits, you can start taming Familiars by approaching Brighterflies anywhere on the World Map. They’re usually located where there are mobs of enemies. A Brighterfly looks like shiny butterflies flying in a group — as highlighted in the image below: Once you see a Brighterfly, interact with it by clicking the “Interact” button that’ll appear beside your skills right after you get close to it. Upon clicking the “Interact” button, an interaction buffer that lasts for about five seconds will then start. After the interaction buffer is finished, a heart-shaped button or the “Tame” button will then appear in place of the “Interact” button. The Familiar will also be revealed at this stage. Here, you can decide whether you will continue taming the Familiar or not. Click the “Tame” button if you want to proceed with taming the Familiar. Or just leave it if you don’t. Upon clicking the “Tame” button, a prompt will appear that tells you the exact type of Biscuit required for that Familiar to be tamed. Click the “Confirm” button if you want to Tame the Familiar: There is a chance that the taming process will fail, so make sure you have enough Biscuits in your Inventory. You only have a one-minute window to Tame a Familiar. After that window closes, the Familiar will disappear by itself. If the taming process is successful, the Familiar will then be added to your collection — giving you either a Familiar you can invest into, or giving you fodder that you can use to get Stretchy, Tough, and Fluffy Jellies.
