You awake in a weird cave with something strange written on the wall. You find a small piece of paper on a rock. It says the following:
Solving each code and entering it into the password entering device, or the P.E.D. for short, will unlock the next room in the cave.
Rules:
I will only accept answers which fully explain their reasoning for EVERYTHING.
If your answer comes up at about the same time as another person's, I will accept the answer based on quality of your work. (Note: I will still upvote both)
Note that it will get very difficult, and some stages may feel impossible to solve, but I bet somebody will solve it, because someone always solves it on PuzzlingSE, and everyone here is awesome at puzzles!
There's technically nothing stopping you from going to a room you aren't on, so I want you to pinky promise to me that you won't. ;)
Codes are in bold
Good Luck!
Room 9 Hint:
This has something to do with morse code.
=========================================================================
Room #1:
A sign above the P.E.D. says eerht-ytfif and .retal lufesu eb yam siht
Room #2:
You see lots of letters on the wall that say XXIV. You also see a carving that says "xis kcab evom"
Room #3:
Carvings on the wall say Tjyuz.
Room #4:
You see a sign hanging from the wall that says Bismuth.
Room #5:
You talk to a man who says "I'm a prisoner here too. Here, take this slip of paper I found 3 rooms ago. I'm not sure what it means, but I'm sure you'll be able to figure it out." You look at the paper and see the text: vrayDBO
Room #6:
You a long plaque taking the whole left wall that says 010101000111011101100101011011100111010001111001001011010101010001110111 01101111.
Room #7:
You find a man, no doubt crazy from being locked in the cave, say that he knows the code, but will only tell you in riddle form. He says The code is of 5 numbers, and each number is different. The sum of all its numbers equals 21. The second number is twice the third, the third is twice the first, and the first is twice the fourth. The fifth number is twice the difference of the third number minus the fourth number.
Room #8:
You find a massive wall with a massive plaque that says: 00110000 00110000 00110001 00110001 00110000 00110000 00110000 00110000 00100000 00110000 00110000 00110001 00110001 00110000 00110000 00110000

You wonder what this long string of numbers could mean. You see another smaller plaque that says URURURURURUXZ
Room #9:
A man says: "I think the last room is next. I just can't solve this puzzle! Here, you try it!" The man hands you a slip of paper which says VI AO CU I B NIJL EGKHJI UIO E AOEH E GA You are utterly confused and do not know what this could even mean.
Room #10
There is a sign that says: You have gone this far, and solved many puzzles, but now you are nearing the end. If you have paid close attention, then the following should be easy. Just as you finish reading it, a panel pops up from the wall. It shows one code: OUR 5mooR 85 11100110011101101001011001101110001101101111011011001110 QVAAMFT. If you can find a way to solve it then you and your new friends can get out of the weird cave and to safety! The P.E.D. comes up through the wall, but this time you can enter letters instead of numbers.
