A number is divisible by 4 if the number formed by the last two digits is divisible by 4.
The number formed by the last two digits of the given numbers is 11.
Now, 11 when divided by 4 leaves the remainder 3.
So, each number can be expressed in the form (4m+3), where m is a natural number.
Hence, statement (1) is correct.
The square of any integer is of the form 4m or 4m+1. So, none of the given numbers are squares.
Hence, statement (2) is incorrect
