You can use pin "Numbers".

But the pins will need to be grouped within 2 full ports, instead of scattered like you've shown.
Preferably PORTB and PORTC.
0-7 is PORTB, 8-15 is PORTC, but they can be changed in the 16F877.bas file.

Code:
for i = 0 to 15
    serout2 i, 8276, ["hello, this is PIN# ",DEC i]
    PAUSE 300
next i
