The first issue is, water parameters. You have listed fish that prefer soft acidic water and others that prefer basic harder water. Depending upon what your source water (tap presumably) is, some may be OK and others not. If you can indicate your water pH and hardness, this will help; you can usually obtain this information from your water supply people, many have a website.
Shoaling fish usually do best in groups of 6+, so bear this in mind when deciding on shoaling fish. In a 37g there is only so much space, and keep in mind the adult size of the fish.
One of the listed fish is problematic, the red minor tetra. This is probably the Serpae Tetra, Hyphessobrycon eques. If you check the profile (click on the shaded name, or use the second tab from the left in the blue bar at the top) you will note that this species is often nippy and aggressive, and should be in larger groups (8*) and either on its own or in 4-foot tanks with other active fish. In a 37g I would leave this species out.
