First is the tank cycled??? You need to do that and if you don't know how there is a section somewhere on the site that tells you. The stocking plan as a few issues. First, the mollys really need a larger tank and salt to maintain good health. Mollys should grow to about 3" at least, so 8 would be crowded. 8 platys would be pushing it a tad, but it is doable with good filtration and weekly water changes. The corys are fine and if you go with pandas or another smaller type you could go 6-7 easy. The bristle nose should be ok, I'd get an albino as they tend to be just a tad smaller. As for the angel, you may have a fin nipping issue. Angels all have very different personalities, kind of like male bettas. Some would be fine while others would be hell on wheels. If you go with an angel your best bet is to get the smallest one you can find and watch it like a hawk for the first year or so. You could also go with a pair of kribs, just for fun one normal, one albino. A dwarf gourami would work well or you could get a group of female bettas.
From your list it kind of looks like the middle of the tank would be empty. You may want to get a small school of harliquin rasboras or maybe cherry barbs. If you get an angel don't even think about the schooling fish.
P.M. me if you have questions or need to know where to get fish. Also, look up celestrial danios, may make a different plan once you do.
