Remove one of the outer toothpicks and one of the dividers of two squares. there you have two SQUARES .
A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares

Start with a 2x2 square (that uses 8 toothpicks) Use the other two to make a 1x1 square in one of the corners of the big one..
17 squares. 1 of size 4x4, 4 of size 3x3, 9 of size 2x2, 16 of size 1x1 Total 30 but that depends on a particular interpretation of the question (16 squares arranged in a 4x4 group). If the 16 are arranged in a row, then they might be regarded as a rectangle and you only have 1 square (the box). If you define the box to be a real 3 dimensional box then the box itself has 6 or 5 squares depending on if it has a lid or not.
Note that the question does not say how the 5 squares are arranged. Let me specify one scenario: ____ |_|_| |_|_| |_| Take the two toothpicks from the upper left corner (the upper-right and the corner right below it will do too) and put them inside one of the remaining squares like a cross +. I can count 7 squares or 8 squares, depending on whether I count the square that contains the + or not. If your question can be more specific about the count of toothpicks, perhaps we can have a better solution. ======================

7 squares is forty nine so you remove two toothpicks to make the digits 49
You make 3-D! Look... 6 squares in one cube and you can do that with toothpicks too!

Make a two by two grid with six toothpicks, and then place the other two toothpicks at a 45 degree angle on the corner of two of the squares.

You arrange 12 toothpicks into a large square, subdivided into four squares : 2 toothpicks on each side and four more, one each from the middle of the sides to the center of the large square. Now you have four (small) squares. Take away 2 adjacent toothpicks from the ones in the center, and you have 2 squares : one remaining small one and the large one that has the small one inside it.
