Code #1
Observations
Numbers ranging form 1 to 5. A greek historian will be your guide
Solution
Numbers ranging from 1 to 5 are a good hint that a polybius square was used. Convert each pair of numbers from this index

Code #2
Observations
Looks like decimal, is it really !!!
Solution
Let’s start by making pairs to see what we are working with
57 53 53 76 74 63 58 69 54 61 56 51 75 74 73 59 54
Somehow we need to convert those 7 to either 5 for decimal or 3 for hex. Using Atbash we can convert those 7 to 3
53 57 57 34 36 47 52 41 56 49 54 59 35 36 37 51 56

Pretty amazing how this code avoided using letters in hex
Code #3
Observations
Long string of letters but with a very specific range.
Solution
Convert letters to numbers using a=0
0 1 10 0 10 10 11 0 0 0 10 0 11 0 11 10 0 0 11 0 10 10 0 11 10 0 0 0 11 0 11 11 0 11 10 11 10 11 0 0 10 10 11 0 11 10 0 0 11 0 11 0 0 0 11 0 0 1 10 0 11 0 0 10 0 11 0 0 10 0 0 11 0 0 11 1
Make groups of 8
