>VIII - Justice (La Justice): a woman, sometimes blindfolded, holding a sword and set of scales. A very traditional allegory of justice, objectivity, rationality, and analysis,
>X - The Wheel of Fortune (La Roue de la Fortune): a six or eight-spoked wheel decorated with elemental symbols and surrounded by different animals wearing wealthy and beggarly clothes. A symbol of fate and varying luck, fortunes, and opportunities, and the cycle of life. What goes up will go down, what goes down will go up.
Best match I could find for Cheryl:
>II - The High Priestess (La Papesse): an old woman with a closed book, a symbol of hidden knowledge, wisdom, female mystery, and magic.
Silent hill itself:
XVIII - The Moon (La Lune): two dogs howling at the moon, around a pool with a crab in it, with two towers in the background. Associated with creativity, inspiration, dreams, madness, illusions, fear, fantasy, the subconscious, and trickery.
Couldn't find an obvious match for Heather's Bum.
