It is given that,
RISE AND GRIND DAILY is coded as 23%@+ 11%%= 29%%= 5@%= -----(I)
MAKE ROUTE HAPPY TODAY is coded as 33%%= 18%@+ 23%@= 45%%= ------(II)
KEEP PUSHING YOURSELF HARDER is coded as 31%%+ 26%%+ 27%%+ 23%%= ------(III)
BELIEVE ON DAIRY PRODUCTS is coded as 7%@= 29@%+ 35%%+ 29%%= -------(IV)
We know that, 
| A | B | C | D | E | F | G | H | I | J | K | L | M | 
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z | 
| 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 
From I and IV,
RISE AND GRIND DAILY is coded as 23%@+ 11%%= 29%%= 5@%= -----(I)
BELIEVE ON DAIRY PRODUCTS is coded as 7%@= 29@%+ 35%%+ 29%%= -------(IV)
From the illustration,
ON = O+N = 15+14 = 29
DAIRY = D+Y = 4+25 = 29
In the words, DAILY and DAIRY,
The first letter and the last letter are consonants. Also, the total number of letters in each word is 5.
From I and II,
RISE AND GRIND DAILY is coded as 23%@+ 11%%= 29%%= 5@%= -----(I)
MAKE ROUTE HAPPY TODAY is coded as 33%%= 18%@+ 23%@= 45%%= ------(II)
RISE = R+E = 18+5= 23
ROUTE = R+E = 18+5 = 23
In the words, RISE and ROUTE,
The first letters are consonants and the last letters are vowels. Also, the total number of letters in RISE is 4 and ROUTE is 5.
Thus, we can conclude that,
Logic for number = the addition of the positional values of the first and the last letters.
Logic for % : The first/last letter of a word is consonant.
Logic for @ : The first/last letter of a word is vowel.
Logic for = : the total number of letters in a word is odd.
Logic for + : the total number of letters in a word is even.
So, the codes are:
| Words | Codes | 
| RISE | 23%@+ | 
| AND | 5@%= | 
| GRIND | 11%%= | 
| DAILY | 29%%= | 
| MAKE | 18%@+ | 
| ROUTE | 23%@= | 
| HAPPY | 33%%= | 
| TODAY | 45%%= | 
| KEEP | 27%%+ | 
| PUSHING | 23%%= | 
| YOURSELF | 31%%+ | 
| HARDER | 26%%+ | 
| BELIEVE | 7%@= | 
| ON | 29@%+ | 
| DAIRY | 29%%= | 
| PRODUCTS | 35%%+ | 
According to the logic,
K+R = 11+18 = 29
The first letter is consonant: %
The last letter is consonant: %
Total number of letters in the word is 7 (i.e., odd): =
