Informality means the state of being casual, relaxed or not formal. You can use it in situations where you want to express that a situation or conversation is not very serious, and you don't need to use very formal language. For example, you might say that a family gathering was very informal because everyone was wearing casual clothes and having a good time. Or you might say that you appreciate the informality of your boss's communication style, because they don't always speak in a very formal or serious way.
