123,456 would be the smallest number using all 6 digits. You arrange the numbers from lowest to highest.
From left to right, pick the smallest possible digit every time. This will give you the smallest possible number.
It is difficult to interpret exactly what you are trying to ask. If you allow your five digit number to have leading zeroes and do not allow negative numbers, then 00000 - 99999 = -99999 is the smallest number. If you do allow negative 5 digit numbers, then (-99999) - 99999 = -199998 is the smallest number.
012345 or -543210, if negative numbers are permitted.
The smallest is 1111 if repeats are allowed. If not, it is 1235.
100122 or, if negative numbers are permitted, -998877
