Hi looks like your getting quite a lot of help but just a few things Id like to throw out there. The main thing being is a lot of your fish choices are quite iffy if they will work sometimes they do and sometimes they wont. Now having one of these kind of mixes is generally okay and easy to deal with but when you have a few fish that can go wrong mixed together it can cause serious headaches latter on.
The mixes I am talking about are - Guppies + Angels + Gourami. Angels and Gouramis sometimes work sometimes dont depends on the fish, Angels and Guppies sometimes work sometimes dont depends on the fish and the same for Gouramis and Guppies sometimes work sometimes dont depends on the fish.
But when thats nearly half your choices and all your feature fish theres a lot that could go wrong and I would rather cut down on the risks in a tank at the start rather than deal with them when something happens. Since in your original post you said not 100% sure on the Guppies why not give these a miss then cut down your Angelfish numbers to just a pair and then get a trio of Pearl Gourami - for me thats the best bet of them mixing very nice calm gouramis and given the size plenty of space for fish that inhabit the same space in a tank. If you start off with 5/6 young angel fish wait for a pair to form then rehome the others you will be able to make sure you get a pair - when your pair form you will see the aggression levels rise to the other angels and its just best for all fish concerned when the pair is left alone.
You could look at swapping the guppies for something like Platies still colourful and easy to find yet less problematic - though I would keep all males to avoid the issues babies can bring.
Also with the Danios - more a cosmetic thing but with Gouramis Angels and Danios a lot of your fish will dwell in the same area. Just thinking maybe a different schooling species that will stay more in mid water to balance out the tank. OR you could add more cories to give the bottom a lot of activity or have a group of cories and a trio of hoplo catfish? Also one last thing with cories stick to one species as they need to school with their own kind for them to be totally happy
