Pretty much any PIC (oh, except the 8 pin) should be able to handle 5
I/O lines plus a smart alphanumeric display.

These LCDs require a minimum of 6 pins, if you use them in 4 bit mode
and use timing rather than BUSY feedback to control your output
speeds.  That's 4 data, one chip select, and an address (for
control/data.  If you want to use the BUSY flag, you need one more
for read/write (and you must switch directions of the data pins on
the PIC side, to input rather than output, when you want to read the
status).  With at least 13 I/O's this should be very possible along
with your 5 other I/Os.  (You can also use 8 bit mode for more speed if
that matters, requiring 10/11 pins depending on whether you want BUSY
feedback).
