Answer:
Literacy to me is an understanding of something. In the case of reading literacy, your comprehension level, understanding of the material read and the level at which you read; i.e. a transitional level versus an advanced level, etc.
In relation to your three specific literacy types, this is how I see it:
Media literacy - Your understanding of the media, how it works, the way it’s presented and the understanding that it is not all objective or accurate all the time. Much of it can be misinformed or biased.
Information literacy - I would couple this with reading literacy in the sense that it’s your understanding/comprehension of the information presented to you, in any format, whether it’s reading, television, audio, etc.
