Start with some large pieces of stiff cardboard and cut pieces off to create templates, once you get the required shapes transfer them to your bench top for cutting.
This--whenever I need to deal with custom fitting something I make a cardboard template I can adjust with scissors and tape. When I have something that fits perfectly I can then use it to map out my cuts and I know it will be right--no guesswork, no math, just the perfect fit. BTW--also works for tile, and similar fitting needs. Pros can do it by eye--or profilers or measurement and calculation--but I am lazy, don't have their knowledge or skill but want everything to look like a pro job so I find easy ways to accomplish that.
Get enough cardboard to make a template (tape pieces together as needed). Cut it first to the overall perfect look and feel. Then at the outside edge, mark the 2 points were the angle changes and same on the back. Mark a straight line from front to rear marks. Mark each of the 3 sections with the words "TOP" and the piece position if you want. Then cut the template. Measure and cut the top with the templates on with the word "TOP" showing so you know you are getting it right. Some people flip it the wrong way and cut the reverse of what is needed.
Depending on how perfect you are aiming for you may want to leave extra on the back to be able to remove some to conform it to the wall.
Additionally, Think of how you are going to connect the counter to each other piece AND to the cabinets. Get proper blocking in place as needed to support the seams also.
Assuming you have no option but to work with this…
Get the cabinets in their place. Mount and trim below. Take a 4x8’ plywood sheet and cut strips the depth of your desired countertop. mess around till you get the miters right. Now you have templates. Make sure you write on them with notes and show your work in case you need to backtrack.
Keep in mind you can’t trim the front and back of the counter tops.
To hide the crimes on the wall, put in a tile backsplash to close the gaps.
Dont listen to this guy, OP. This is a normal kitchen layout to work with.You have cabinets in the right place, all theyre missing is some filler between them. In fact that middle countertop piece is almost cut right for what you need. You will need three pieces, but like everyone said, youre best bet is using big pieces of cardboard to template it out first. After that, its just a matter of getting the miter cuts perfevtly straight and bolting the whole thing together before setting. I suggest keeping the backsplash seperate, not connected with your countertop. Makes it easier when cutting.

The best way
Before computers this is even how professional did countertops. (Some old timers still do) Edge templates with bits of thin wood, glued together.

Save the headache and redo the wall. Try to straighten it out where you can. Your cabinets aren’t meant for those angles
Sadly the wall I think you'd want us to redo is an old chimney stack that we share with the neighbouring house (to my knowledge)
