This seems to be in leetspeak format. I manually was able to convert it, but you can use a website such as this one to decode it. I then got the flag:
01101100 01100101 01110100 01110011 00100000 01110100 01110010 01111001 00100000 01110011 01101111 01101101 01100101 00100000 01100010 01101001 01101110 01100001 01110010 01111001 00100000 01101111 01110101 01110100 00100001
This seems to be in binary format. I looked for a binary to ascii converter online.

To me, this seemed to be Base32 or Base64. I tried Base64 and it did not work. I then tried Base32, I then got the flag:
RWFjaCBCYXNlNjQgZGlnaXQgcmVwcmVzZW50cyBleGFjdGx5IDYgYml0cyBvZiBkYXRhLg==
For this one, the last two characters "==" led me to believe that this was Base64, and this led me to get the flag:
68 65 78 61 64 65 63 69 6d 61 6c 20 6f 72 20 62 61 73 65 31 36 3f
To me, my first thought was this could be hex because of the "3f" at the end. My intuition was correct, and I got the flag:
Ebgngr zr 13 cynprf!
For this, I tried ROT13, and got it on the first run:
*@F DA:? >6 C:89E C@F?5 323J C:89E C@F?5 Wcf E:>6DX
For this one, I used this writeup to get help for it and found out it was rot47:
- . .-.. . -.-. --- -- -- ..- -. .. -.-. .- - .. --- -.. -. -.-. --- -.. .. -. --.
This seemed to be morse code for me. It was!:
85 110 112 97 99 107 32 116 104 105 115 32 66 67 68
For this CTF, I assumed that this would be ASCII because of the numbers above 100. I got the flag after I entered this into an online decoder:

For this one, I got some help from this writeup. This one had multiple ciphers in it.
This led me to the answer:
Task 2: Spectrograms
The hint for this message was Audacity. I then downloaded Audacity, and then got the flag:
The way to get the message was to click on the arrow next to the .wav file and then clicking on spectrogram.
Task 3: Steganography
For this problem, I did get stuck and used a hint from here. I then typed in the command:
steghide extract -sf <filename>.jpg
It then asked me for a password. I just pressed ENTER and then it allowed me to get a file that had a flag in it:
Task 4: Security through obscurity
The image by itself shows this:
I then used the following command to find a couple files:
foremost -i <filename>
This led me to find these files:
That eventually did not lead me anywhere. HOWEVER, when I ran the strings command on the file, I got the answers needed for the CTF:
