Code #1
Observations
This one uses the regular cipher but spotting the keyword is not easy. REGEX is your friend to guide you
Spoiler
Assuming letters are using 2 characters, prefix and suffix would use 15 charaacters. We need to find a 7 letter keyword. Use the REGEX search ^[nhcifwthtcqetsveiviyoi]{7}$ to get the only possible keyword: Voynich

Code #2
Observations
Check how many characters you have and why they used exactly these characters
Spoiler
There are 136 characters in the string, excellent for groups of 8 and the 01 at the start is a good hint for binary

Code #3
Observations
Capital letters, lowercase letters and numbers. This should be enough to point you in the right direction
Spoiler
The two capital D are sort of hinting at Base64. Look at the numbers, if you make pairs they can convert from numbers to letters using a=0
yDb 16 m 25 03 22 00 g 11 18 01 g 11 22 02 25 iDoh 07 22
You need to change the case of the lowercase letters, capital letters convert to numbers and numbers to lowercase letters
