Shown below is number 10 formed with 5 sticks.
1 Move exactly 1 stick to get the smallest non-zero positive number.
2 Move exactly 1 stick to get the largest non zero positive number.

For the largest number,
Move the top right stick to the bottom left to create
ω, a representation of infinity.
For the smallest,
Do the same and rotate the view 90° to create
ε, an infinitesimal, which is the smallest nonzero positive number.
For 1, if we are allowed quantities with dimensions, then we can form
1 / c, where c is the speed of light. Using standard units gives approximately 3x10-9 s/m, i.e., the number of seconds it takes light to travel 1 meter. However, we can further make this number arbitrarily small by using arbitrarily small units of length or arbitrarily large units of time, e.g., the number of yottaseconds it takes light to travel one Planck length is approximately 5×10-68.
For 2, we can form
1 / c as before, but now creating arbitrarily large numbers by using arbitrarily large units of length or arbitrarily small units of time, e.g., the number of Planck times it takes light to travel one yottameter is approximately 6x1058.
For the minimum number:
Move the stick at the top of the 0 to the left, so it connects the 1 and the left stick of the 0. Rotate it 90 degrees and it's a 2.
For the maximum number:
It doesn't specify how far you have to move the stick. Move the stick of the 1 slightly over, so it's still a 10.
For the largest number:
move the top matchstick to the empty bottom spot to form a "w" shape indicating omega (the ordinal number).
For the smallest number:
move the singleton matchstick below and to the left of the "zero" matchsticks to form 1 to the zeroth power, i.e., 1, the smallest non-zero ordinal.
