2s complement can be taken only for signed negative numbers.
So,
00000101 is +5.
11111100 is signed negative number so convert into 2s complement it gives -4.
11111000 is also a negative number so convert into 2s complement it gives -8.

00000101 positive msb (0) so +5.
Rest two binary numbers are negative because msb is high. So take 2's complement and convert in decimal with negative sign.
