I’m at work so forgive the short hand answers...
Your not stupid for forgetting to mention he’s a juvi male veild, I’m sure your drowning in thoughts right now. No one is born with this info, it must be learned...
Chameleons do not take change well, I’d advise moving him every weekend or two. They have evolved to blend in, this is their main defense against predation. That means all that attention and handeling will trigger him to panic and try to escape. Him not being able to escape will compound that stress even more.
One thing I try to make newbys understand is that chams are not pets, they are a hobby. Or at least a look but don’t touch pet. 80% of them want absolutely nothing to do with humans, especially male veilds. That’s not to say you can’t handle him, but it’s your Cham that decides how much handeling he will allow, he sets the pace. You can build trust over time by teaching him to associating you with positive experiences like hand feeding, and when he’s ready, trips into the sunshine. On the other hand there are some chams that will never tolerate handeling no matter what you do, it’s a total coin flip.
This forum is the #1 resource for all your chams needs, proud of it. If you google anything about Cham husbandry 80% of the results will lead you straight back here!
I’m going to make gutloading easy for you, go on Amazon and buy Cricket Crack. Mix water in until it has a peanut butter consistency and serve it any feeders, no other water source required.
Do not do the cricket cage as mentioned above, I’ll come back to this question later.
As mentioned above chams need time to bask after eating to digest their food. All feeding should be done by noon. You can throw one or two in after you get home from school but no more. If you leave for school before his lights come on just start by throwing 7-8 crickets in his viv on your way out. He will wake up and hunt them down when he’s ready. This also allows him some stimulation through out the day. Post a pic when you get him and we can give you a better idea of how many crickets he should eat a day.
It would be better to have someone feed him in your absence but it won’t hurt him to miss a feeding every two weeks. Or just throw in two days worth of food when you leave. The real question is how will you water him when your gone fore a couple of days. I recommend you install a Mistking, worth every penny.
Your Cham comes with an immune system, let him exercise it! You don’t have to run around behind him and clean every poop as soon as it hits the floor, however that is the best practice. As a juvi he will likely poop daily so I would not go more than 2-3 days. As he matures he will start pooping about once a week and may even potty train himself, making your job even easier. A mother option for keeping his viv clean is to set up a bio active viv. It is a bit of an advanced topic so I’ll let you research that on your own time.
Now that I’ve answered your questions, I’d like for you to answer all those questions I posted originally to see how much you’ve learned!
