The Bolivian Ram should be fine. It is not near as difficult as the common Ram, though it does not like unstable water conditions but that is something else. If you can get a true pair, fine; two males acquired together for a 55g should be OK. Not easy to sex young. If you can find a store tank of fish, observe their interactions, this can sometimes clue you in to sexes.
In the case of the Cockatoo Dwarf Cichlid, it depends on where the fish came from respecting water parameters. As noted in our profile, wild caught need soft acidic water, but tank-raised fish will manage in basic as that is likely what they were raised in. Check the profile. This species is best with one male and 2-3 females.
You will still have room for another upper-water shoaling fish. And remember, both these cichlids are fish that remain just above the substrate. I mention this not due to issues with loaches, but thinking solely of fish in various levels in the aquairum.
