Generally speaking, gourami should be kept with fish that are fairly quiet and sedate, like themselves. Rasbora are excellent for this. Danio and barb tend to be active swimmers, and this in my view is not good pairing. Characins would depend on the species; some will nip fins so they would be out (Bleeding Hearts have been known to do this, one of our members had a group of these in with angels and she had to remove the tetra due to the angelfish fins getting nipped mercilessly). This tetra is in the Rosy T clade, and some of the other species in this clade are fine, like the Rosy Tetra, Roberts Tetra, Black and Red Phantom. At any rate, these should be OK, sometimes something will affect even peaceful fish to get nippy.
The male/female ratio of one/three is good, but as someone pointed out, this sometimes doesn't work. Male gourami are really very similar to male cichlids in their sense of territory and related aggression. Having multiple tanks just in case one needs to separate them is advisable, or a store that will take them back. All female should be OK as far as I know.
On the pictus catfish, a group of five is better. And this fish is predatory. Check the profile.
