Sounds like you’ve got a good grasp on things so far. I’ll probably tell you things you might already know, so just smile and nod if you need to.

The minimum size enclosure for adult chameleons is 2x2x4’, so as long as you have that, it’s fine. I just like encouraging people to go larger
if they can.

Keep adding branches and make sure that they are of varied diameter to keep those mitten feet muscles in top shape. My personal rule is to go as thick as my loppers can cut thru. I have no trees, but my neighbors do and get them trimmed regularly. They are probably used to seeing me scavenge thru their trimmings pile and dragging limbs across the street.

It sounds like you don’t measure temps or humidity yet. It is important to know both. Ideal daytime temps for a mature male veiled is about 85. At night you want a good temp drop and if you can get it below 68-70, perfect. Ideal daytime humidity is between 30-50%. If you are able to achieve that perfect night time temp below at least 68, you can run a humidifier at night to boost humidity all the way.
For feeding, it would be good to add more variety. For many of us it takes a bit to get used to the idea of roaches, but they are great feeders. Dubia and discoid are quite easy to keep and adults are unable to climb slick surfaces and don’t fly even though they have wings. Silkworms are my favorite feeder and are very nutritious and hydrating. It can be a bit challenging to find them available. Fram’s chams sells them. Grasshoppers are a great feeders, but only a couple of sources for them. Here is one.
https://dragonhoppers.com/ They are a bit meatier, so one hopper is equivalent to maybe 2 crickets or roaches or so (depending on size). It’s fine if your guy doesn’t like wax worms. They are just fatty treats, like reptile candy. Most do like superworms for treats. Those are fatty and addictive. Hornworms do have some calcium in them, but are primarily hydrating treats only. You can feed the moths, but it possibly could be too large for your guy to eat.
The orange cubes are ok for hydrating your feeder insects, but not great for nutrition. The healthier your bugs are, the more nutritious they are. Fresh veggies, greens and a bit of fruit are great to feed them. There are some commercial preparations that are decent, like Repashy Bug Burger.
For supplements, you want to use a phosphorus free calcium without D3 lightly dusted at every feeding. While there are several different ways to provide vitamins and D3, the easiest and most common that we suggest is to use either Repashy calcium plus LoD or ReptiVite with D3 one feeding every other week (or twice a month if you prefer).
Sorry if I have told you stuff you already know. I can be like a mother hen.
