Answer 1

Base 16 - 4 bits
Base 64 - 6 bits
Accordingly, we read three characters from the right (12 bits) from the string, consider them as an integer, divide into two parts of six bits, make up part of the new string from two corresponding characters. Taking the 64-digit alphabet [[email protected]#]
568be27e005bd6b61a8b4567 ₁₆
567 ₁₆ = 0101'0110'0111 ₂ = 010101'100111 ₂ = Ld ₆₄
8b4 ₁₆ = 1000'1011'0100 _{2 =} 1010 Yq ₆₄ ... 568 ₁₆ = 0101'0110'1000 ₂ = 010101'101000 ₂ = Le ₆₄
568be27e005bd6b61a8b4567 ₁₆ = LelYVW1RrROQYqLd ₆₄

Answer 2

your string is a number in hexadecimal notation. We translate into a number system with a higher base (64 for example) and rejoice.

Answer 3

As they write to you in the comments, most likely, this is an encrypted set of characters (password, something else). MD5 cannot be decrypted using PHP, and in general, as far as I know, you can only use rainbow tables (already generated hashes).
