I have a kitchen wall with a window on top, below the window are 8" concrete

I will be installing a kitchen sink and dish washer along that wall, so I
broke the wall on one side to run the 2" PVC pipe to a vent stack to the
right. *The PVC pipe run is over 4 feet long, and in order to run that pipe
and the one below for the dish washer, I had to literally break off one side
of that concrete wall, so that resulted in half the length of that wall
being supported now with just the outside face of the old concrete blocks..

Any idea what is the best way to patch it up? *Do I get 4" thick blocks and
built up the front side? *Do I frame 2x4s to support it? *Do I use ply wood
to cover the front side and pour solid concrete?

You've gotten advice on how to repair it, I'll give you some advice on
how to avoid some of it.

Instead of blowing out all of the block, you could have removed the
front face of just one course of block for the horizontal run.
Running a diamond bladed circular saw or cutoff saw horizontally would
control the depth fo the cut when you start breaking out the pieces.
One course height would allow you to have the two horizontal runs and
allow for your pitch, and to use bricks, cut block or 4" block as the
infill.

Reminder: Ask the question before doing the work. That way someone
might be able to save you some time and money. After-the-fact
solutions always cost more and take longer.
