I would agree that it may not today be overstocked, but there are some very serious problems with the fish stocking and things will become problematic sooner or later.
Two angelfish will fill a 29g, if they are a mated pair; if both are males, eventually one may end up dead.
The characins are shoaling fish that must have a group, as someone else mentioned. Not only is this best for them, but on their own characins frequentlly become stressed and aggressive, and nipping the angels is almost a certainty in time. The angels will also see some of these fish as food, so it is a two-way street.
Rummys (Hyphessobrycon bleheri) are one tetra that is always better in larger groups, and I would say never fewer than 8, but 12+ is better still. I'm not suggesting that here, as the tank is just too small for all these fish to be in proper-sized groupings plus the angels. The corys need more too, no less than five. And kuhlii should have at least three, though five or six would be better for them too.
