looks like a 3 cabinet build to me
You'll need the upper and lower on the far left, and one upper in the center above the fridge.
You can look at the old ones to see how they were built. Your upper cabinet needs to be longer, and deeper, also the left side upper, so no "shrinking" there.
The main issue I see, setting aside your "inexperience" is the lack of a workspace. I've done a lot of cutting outside under canopies and awnings, but it ain't a good environment.
A cabinet build is really more about organization and somewhat less about the actual making/cutting in my opinion.... making the drawings, figuring out the dimensions, making a cut list, figuring out the panels on the plywood to minimize waste, double checking everything, is the key to a successful build.
Having accurate machines and making accurate cuts is another issue. Small tablesaws with minimum tables don't make for great accuracy. A circ saw and an edge guide is a "tedious" method and requires patience to measure twice, cut once. Making the raised panel door panels, rails and stiles, is another issue, and requires some practice trials on scrap to get things just right.
I would not say "Don't try it", but those are the issues I see. There is plenty of help here, but IF the wife is anxious about gettin' them done, that can be another issue. Another approach I would consider is finding stock dimension cabinets from a supplier, that can be modified either by making new doors or by adding side frames to make the dimensions work.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
