Check the ingredients list on the canned coconut milk.  If there's any form of sugar - HFCS, corn syrup solids, sweetener, that kind of thing - anywhere in the list, don't buy it.

If you're currently on a limited budget, see if you can get 70-75% ground beef.  It's tastier, and more filling per dollar.

Also, organic isn't that important if you're on a limited budget, except maybe for eggs.

Any advice regarding how many apples/bananas I can eat in a day?

These two (apples and bananas) are actually quite dangerous: they've been bred to have a lot more sugar than they did as wild fruits. Bananas, in particular have been definitely bred by humans (in their current form they can't reproduce normally, they are cloned). A quick test for fruit: vitamin / sugar ratio. Apples have very little in way of vitamins you can't get elsewhere and still have a high amount of sugar (glucose and fructose). Same with bananas, although they have a little more starch than sugar.

With that in mind, how many you should eat will depend on your activity levels for a given day and what you are trying to achieve fat-loss wise. For rapid fast loss, avoid them and replace with berries and/or other better choices.  After high intensity training, 1 or 2 pieces would be ideal to replace muscle glycogen.

Men can usually lose excess weight eating as much fruit as they feel like, but you'll lose weight faster with less fruit.  Limiting fruit might be a good idea because of the diabetes, too.

When I first went paleo, I'd often eat half a dozen bananas in a day; now I eat a few strawberries or blackberries on average.  That might give you a feel for the range.

For breakfast eat eggs, sometimes add chopped spinach, from loose cut up frozen.
  no fruit for breakfast.  Only protein, with some spinach.  Or eat a hamburger. 
 
You will not get hungry only eating the protein.   Good luck..

Finally got some money and got about half the items on my list. I can tell canned tuna is a problem for me. I mean, it's my crutch. I realize it's not the best food to eat considering Hg. How many 7oz cans per week is too many? I can eat one can every day if I'm not careful.

Oooo, I love sardines! I had a couple cans in my hand but put them back because I wasn't sure.

I know canned food isn't the best but I like to have food on hand for when I can't get to the store.

And anything with the word "sauce" in it. Stick to those canned fish that clearly say: packed in water.

I've been strict with my canned tuna for as long as I can remember. I hate oil-packed fish. Yuck!
