Ok, again, in what size tank?
What kind of africam frog - dwarf or clawed? Clawed will not work long term with any of the fish and dwarf would likely be killed once the angels mature and start becoming aggressive.
How many angelfish is 'some'? Depending on the tank's size, this is very important as most gouramies and angelfish spend their time in the same water level so would clash in a smaller tank.
Now getting a male and female of each is not an option unless you have a realy big tank. If you want to keep all those species, some changes will have to be made.
Firstly, a pair of dwarf gouramies would work but it's unlikely that you'll find females. A couple of males would work if that's the case. If, on the other hand, you are one of the lucky people who have access to the dull-colored females, get yourself a trio - 1 male, 2 females. That's a much better option for everyone. Just a warning, dwarf gouramies may get bullied by aggressive fish (breeding angels for example), with these semi-aggressive fish would be best skipped altogether and are known to be quite prone to disease. I would personaly say you are better off not getting any dwarfs at all. Maybe get a single male banded gourami (colisa fasciata) instead. They look very similar but grow larger (to 4").
A pair of pearls should be fine though only if you have a big enough tank so that the angels, once they pair up, do not harass them. They may also get nipped by the loach if they stray too near the bottom of the tank.
Like I said before, the gold and blue gouramies are the same exact fish - just different colors. As such, don't go for a pair of each as the males become very territorial and aggressive. in fact, you'd be better off going all-female as the males would also likely bully the pearls once mature. If you are willing to do so, get just 1 of each color (both female) or you are realy looking at a very big tank.
Assuming you ended up with the following fish (which is your best option), you would need (at least) a 55 gallon tank:
RTBS
pleco (if this is a common - or another large plec - it'll need to be rehomed once it starts growing as they get to 18").
zebra loach
pair of angels (you'd have to start out with around 6 and then keep the two that pair up - return the rest)
female gold gourami
female blue gourami
pair of pearls
male banded gourami/trio of dwarf gouramies
