A segment refers to the one line of a 7 segment display .... you are controlling every one of those individually with the 1s and 0s in the bitmap B10000000 etc....
i want to control every single segment for example the first "1" the second "2" ....
If you mean you want the first digit to be "1" and the second digit to be "2'" then depending on which way they have wired up the segments ( I will assume here a,b,c,d,e,f, dec.pt )
for a "1" you would shiftout B01100000 ( only segments a and b on )
for a "2" you would shiftout B110110100 ( only segments a, b d,e, and f on )
