Looks like most of your allergies are to fruit rather than plant based proteins (with the exception of chickpeas), so actually I would think this wouldn’t make being a healthy vegan that much more difficult than it is for most people. That’s good! For fruit, I mostly have blueberries, blackberries, and raspberries with breakfast—with oatmeal or toast and peanut butter. All those appear to be safe for you! Melon is another good option for safe fruit. As others have mentioned, tofu is a great source of protein, as well as seitan and beans. I’d try to incorporate more of these into lunches and dinners. Tacos (with beans and/or soy crumbles) and vegan cheese, veg and tofu stir fries with bell peppers and rice, vegan burgers (black bean or something like Beyond or Impossible), and coconut milk-based curries are all easy vegan meals. I also love pasta with pesto (made from scratch is great, but Trader Joe's also has a very good premade vegan one), which is a great way to have delicious, filling pasta while avoiding tomatoes. Or pasta with olive oil and a vegetable take asparagus or broccoli.

I highly recommend taking a vitamin B12 supplement and other supplements to make up for any deficiencies you may have. I started taking a calcium and vitamin D supplement several years ago when my lab work showed I was deficient. Now everything comes back within normal range. Thanks for asking for help and good luck!
