Caliburn is actually the sword that was put in the stone, not Excalibur. Caliburn was the sword used to test to see who could pull it free and become the new king of Britain. She was only given Excalibur from the Lady of the lake when she became of the approriate age to rule, which I believe would be 21. Once she had Excalibur that was when she stopped aging.

About the height thing, some people actually do maintain their same height from their teen years. I've been 5'4 since I was 16. I'm 28 now and still 5'4 so the same case could have happened with Artoria.

The MHXs though. They're just parodies from alternate realites like you said, so not meant to be taken seriously.
