PIC16C84 can be configured to have 9 PWM channels
BUT you need to supply MORE information !
What frequency or frequencies do you require ?
Fixed or variable.
PWM from 0-100% or fixed % points ?
if variable , what is the desired update rate?
resolution ? 4 bit,8 bit, 10, 12, 16, 24 bits ?
How are the data to be decided ? Preset or input ?
If input, via RS232 (serial), wireless, encoders, dip switches?
I believe CCS supplies an example in the examples folder..ex_patg.c.. it's a 'pattern generator'
I'm sure others can think of more points to ask, these are just some basic ones.

If you want hardware PWM channels, go to this Microchip page:
https://www.microchip.com/maps/microcontroller.aspx

1. At the top, in the CPU box, select the type of PIC that you want,
such as "8 bit PIC".

Wait a few seconds each time you change something, because it takes
time for the page to automatically reload with the results.

2. Go down to the Digital Peripherals section, and set PWM Chan = 9
in the left column. Don't touch the right-side column.

Wait for the page to reload. You'll see 16F1527 and 16F1526
in the box at the top right of the page.

The only problem is they are 64-pin TQFP and QFN packages.
If you're a hobbyist you may not want that.

and, for 'larger' PIC's, almost any of the PIC24's etc..
These support 'output compare', rather than the simpler PWM, which can be configured to give PWM functionality, as well as CCP's. Many have this on almost every pin!.
