A square is a rhombus. From 1, since diagonals bisect, can we not say that the quadrilatoral is a square?

...not necessarily, the diagonals can bisect to form a 90-degree angle without necessarily having a square. To prove to yourself draw 2 lines that intersect at 90-deg and make one of the lines much longer than the other, then connect all the ends to form quadrilateral... this is not necessarily a square.
