First, welcome to Troical Fish Keeping forum.
I realize you are not considering all of these different fish together, but some of the mentioned fish cannot be housed in a 10g at all. Angels, loaches (except the dwarf loach), sharks, and most plecostomus (the common pleco reaches 12-18 inches) are potentially large fish that in the case of angels and loaches must be in groups (or a mated pair in the case of angels) and require tanks considerably larger. Potentially large fish kept in too small an environment develop stunting issues which cause internal organ deformity, lower resistance to disease, and other issues. The size of the "space' is one thing, but the water quality that comes with it is probably even more significant.
In a 10g, one group of one of the small tetras, rasbora, danio would work, with a group of corys for the bottom. I', thinking 3 corys, and six of the others. Livebearers will work, but if you have male and female you will have hundreds of fry in no time, so be prepared. Barbs are an active swimming fish, and I would personally not house them in anything less than a 20g long. Gourami carry problems depending upon species; some males are aggressive, some need to be in pairs, some get too large for a 10g.
