You need instructions for what they mean. Without instructions for how to interpret, the problem is meaningless. What does "1 down" mean? What inputs are possible in each box? Is it talking about the measurements of the "squares"? Is it talking about sums of digits?
Then, unfortunately, it is a meaningless puzzle unless someone wants to make up instructions for it.
For example, suppose the boxes contain the digits $a,b,c,d,e,f,g,h,i$ like this:
$\begin{bmatrix}a & b & c \\ d & e & f \\ g & h & i\end{bmatrix}$
And we interpret the instructions as:
$100a+10b+c = (100a+10d+g)^2$
$100d+10e+f = \dfrac{9}{4}(100a+10d+g)^2$
$100g+10h+i = (10f+i)^2$
$7|(10b+c)$
We find that we must have $a=0,b=4,c=9,d=0,g=7$. But, this gives a non-integer for the second equation. So, this is not a valid set of instructions.
How about $a,...,i$ are positive integers? And we have:
$a+b+c = (a+d+g)^2$
$d+e+f = \dfrac{9}{4}(a+d+g)^2 = \dfrac{9}{4}(a+b+c)$
$g+h+i = (f+i)^2$
$7|(b+c)$
Now, we can pretty much have any integers we want for at least 3 or 4 of the variables and it will still solve the puzzle.
So, we need enough restrictions that we find a distinct solution and enough freedom that at least one solution exists. Without the proper instructions, it is unlikely that we will ever find a solution.
