Solutions (1-5):

Logic:Words are arranged from right end and numbers are arranged from left end. In each step one word and one number are arranged.

Word – Words are arranged in ascending order from left to right according to the English alphabetical order.

In the first step the word starting with the letter having higher place value in the English alphabet is arranged first on the right end and also the letters of the word are arranged in increasing alphabetical order within the word.

Number – Numbers are arranged in ascending order from left to right.

In the first step the highest number is arranged first and then in the second step 2nd highest numbered gets arranged and so on till the last step and also after rearranging the numbers add 5 in the even number and subtract 5 in the odd numbers.
