of course it matters, whether it's a guppy or an angelfish, if the water quality is poor, the fish will suffer. i believe that angelfish are very sensitive to water conditions, so you have to make sure the water is perfect. how are your water conditions?

yes angelfish is quite sensitive to water conditions. and yes almost all fish will die if the conditions are poor
no i let it run for 4 weeks before to add fish. the first fish i got was 2 neon tetras, 2 male guppies, 1 female guppy, 1 silver molly, 1 black molly and two harlequins. i have now got a hell load of guppies and silver mollies and ofcorse an angelfish.
Angels will do fine as long as the ammonia nitrite and nitrate are kept in check. They dont need soft acidic water unless they are imported wild fish. Most angels these days are domestic bred and actually do better in moderately hard water, plus the hardness prevent PH swings so it really makes more sense.
The crucial thing is to acclimatise them slowly over an hour or two by replacing small cups of water from the bag with tank water.

First you should read about those fishes you're going to keep. It just not water that you add into your tank: Some fishes prefer hard water than others. Some hard water fishes die easily when kept in soft water. (Osmotic pressure is key idea.)
Go to some library and find some magazines and basic literatures about "how to keep aquarium successfully".
When pH is over 7, then there could be ammonia (NH3) in water and you should check it too. Nitrification starts from NH3/NH4+ -> NO2- -> NO3- and maybe then N2 - it usually not happens in aquarium...
NH3 is very toxic to fishes
NO2- is toxic (causing ingreasing metahemoglobin)
NO3- is less toxic but it should be lower than 15-20 mg/l. Although there must be some NO3- for plants. 2-10mg/l is great. However some plants doesn't tolerate even as high as 5mg/l. To get rid of high NO3- level is changing water, making partial water changes.
N2 is gas..
Shoal fishes are kept in shoal, not in pairs or something like that. Neontetras shouldn't put in the same tank with angels -> Angels probably eat them.
If your water is hard and is basic (as they usually are basic), then it would be easier to keep fishes that live in hard/basic water naturally. Softening water is hard and could be very expensive. If your KH is high, you can try to filter it through turf (natural, not fertilizers) trying to soft it. It doesn't really affect GH.
You can also decrease pH by sulfuric acid, but... If you don't know what to do, then it's better to do nothing before knowing what is doing. When changing GH or pH, it should be done slowly. pH is logarithmic and changing pH from 8 to 6,5 means, that you make water 32 times acidic.
