First off, you're on the right track!
I've answered your questions below and added in Tabbcatt's comments so I can respond to those as well.
Sorry for the novel
I did the calculations with the frankenprey calculator and this is what I got:
The first thing I want to tell you is what I wished someone had told me right off the bat when I started my kittens on raw - don't stress too much.
Seriously. The goal of raw feeding, especially frankenprey, is balance OVER TIME. It doesn't have to be perfect every meal/week. Don't get stuck to the numbers on how much to feed him either, learn to read his signals - so you can tell if he's ACTUALLY ravenously starving and needs a bit extra, or if he's fibbing to get extra nummies.
Adjust how much he gets by how he's gaining weight, but don't give him less until he hits about a year, chances are if he gets a bit tubby he'll just run it off. Most kittens will self regulate to some point. (Some won't, fair notice. My Muffin used to eat until he puked, then do it again and again until I removed his food. I just fed him the same as his brother and no more.)
So anyway, I bought some meat and came up with a menu for his first week.
--Adding more to the menu besides chicken is a good idea.
Agreed. You need a minimum of 4 steady proteins, more is better. With raw feeding variety is absolutely key. Each different kind of meat has different nutrients and vitamins, so the more variety the better.
That being said, adding in many kids over a few weeks isn't a bad idea. If you start off his first 4 meals with 4 different meats and he gets the runs the next day you've no idea WHAT caused it. So, for week 1 your plan looks good.
Aim to intro a new meat 1-2 meals per week for the first bit. The more variety he tries the better, but add one at a time. He's in a crucial period where he's learning what 'food' is, if you don't give him much variety he'll never be open to trying new things.

Good plan. You're right on with dividing the organ up, often organs can upset their tummies, so smaller amounts at first is a good bet.
I want to have one canned meal for the next week or two to help him move onto raw.
IMO frankenprey feeding is all about getting what you can when you can. buy bulk when you can afford it, and store for later. I'm lucky enough to have a company locally I can order from, I order an extra 3-5 lbs every month, and then when I really need to I can take a 'free' month when my budget is kinda rough. Keep your variety in mind, but know that if you have a really bad month eating only chicken won't hurt him - every month is a no-no, and really try not to do it, but do the best you can with what you're given.
- I'm a bit worried about him getting enough bone.
Bones. I'd rather use the real deal. Crushing bones first with a hammer in a baggie is one idea. Bones contain more than calcium, magnesium, phosphorus and other minerals, it also contains the marrow, which is very nutritious. Hard to find supplementations to replicate that. Or you could try feeding commercial mice, if that's an option, or feed smaller birds.
I'm with Tabbcatt - real bones are the best. Crushed eggshells are ok, but it's very much a stop-gap. Since growing kittens need calcium more than an adult cat would, this is a pretty important piece as well.
He can definitely do wing tips, the middle bit of the wing (with two bones), chicken ribs, and Cornish hen bones (except the leg bones).
You might need to crush the bones to start with, use a hammer or meat mallet to pulverize them within the meat, but try and let him crunch some of it as it'll build up his jaw strength. When you feed bone in meals with crushed bones to kittens, IMO, you need to be present for supervision. Don't step in unless he's truly and honestly in trouble. Coughing stuff up to try again is normal, don't interfere unless he's truly in distress. But you should be there in case a piece of bone gets wedged in.
- About the salmon oil,when should I give it to him? It says for a cat you should give 5ml(about one tea spoon)/day. I assume that's for an adult cat, how much should I give to a kitten? Are there any alternatives to the oil?
If good salmon oil is out of your range you can buy whitefish/herring/sardines in WATER to give him. Don't get the 'in oil' or 'spiced' varieties. IMO feeding small fish whole is a good idea for him all around. There's tons of vitamins/nutrients in fish - but no more than twice a month and avoid large fish.
- This one's about the kidneys. Where I live I have a hard time getting internal organs, but I know that you can buy pork kidneys at the store (sometimes you can get beef too). can I use those for the 5% other organs part?
--Pork kidneys. You can feed it
Tabbcatt has good points on this as well (most things really
I will note that while Trichinella is a risk...it's a fairly low one. To the best of my knowledge (and, trust me, I looked) it's never been proven that anyone has caught it from their cat for sure. There was always another possible source. Even if you DO get it, it's only really bad if you're also pregnant at the time - hence the common bit about pregnant women not scooping litterboxes.
that being said, caution is never a bad idea and I'd also suggest freezing the meat to -20 for 2 weeks prior to feeding unless you know the farmer and feel safe eating/feeding the meat without freezing.
I'm also a fan of as many organs a you can get your hands on. Variety is the spice of life - and frankenprey feeding.
- Any other food items I could add to his menu?
--I also feed a bit of canned with the raw, it helps one of my cat to try his raw meats after licking his plate around, and it helps as I also add in the fish oil supplements in there (with a bit of water).
I'm also a fan of continuing with some canned feedings. That way if you ever go away and have to leave him with a sitter who refuses to feed raw (which has happened to many raw feeding friends of mine who have to depend on friends/family to care for their pets) you have an easy option. A week of canned food won't hurt him, or ruin his diet. Having nothing to feed him because he doesn't think canned is food any more and your family/friends won't do the meat...not good.
Again: variety, variety, variety. The more kinds of meat you can get him the better. My guys REGULALRY get: chicken, turkey, duck, pork, beef, moose/elk/deer, lamb, llama and alpaca, canned food of many varieties (every other week or so they get to split a big can between the 4 of them - ignore the ridiculous guidelines on most canned foods if you're feeding supplementally to a raw diet), and occasionally fish.
You're on the right path for sure - just don't stress and balance it over time.
