I know that the universe is 13 billion years old and the fastest anything could be is the speed of light so if the universe is expanding as fast as it could be wouldn’t the universe be 13 billion light years big? But I’ve searched and it’s 93 billion light years big, so is the universe expanding faster than the speed of light?

Impossible to know since we don’t have a clear reference nor a way to measure distances in space. Not to mention the our telescopes are useless to see the infinite universe.
To assume the universe is expanding, you ale have to assume the Big Bang theory, but that is just one of many, and of course Impossible to prove.
Anything related to Space is mostly fantasy.
