Right so thats 55 US gallons what filter do you have on it? Basically Ill go through this list you posted and give you my comments on each - here goes
penguin tetra - should be okay
coloured glass fish - I would suggest you never shop at this store again, these are tattooed fish and it is a terrible practise in the hobby
flowered parrot fish - Hybrid fish but if you like it okay, as long as its not dyed what colour are they?
red eye tetra - should be good
fire mouth cichlids - should be good - but community will need to be considered
asorted cichlids - could include any of 1000 or so species so need to narrow down specific fish, although I have a feeling these will be assorted african cichlids which is a different route of fish with quite specific needs
convicts - similar to fire mouths but with more considerations as they are to aggressive - I would avoid them
oscars - to big for the tank need 75g for one and over 100g before you think of other tank mates
kibensis - same as firemouth
jewel cichlids - same as convict
sunset platys - fine, but if you mix male and female you get tons of babies
swordtails - fine, but if you mix male and female you get tons of babies
red platys - fine, but if you mix male and female you get tons of babies
milk calico platys - fine, but if you mix male and female you get tons of babies
sunburst micky mouse platys - fine, but if you mix male and female you get tons of babies
tuxedo sunset platys - fine, but if you mix male and female you get tons of babies
butterfly fish - could work well but community would need to be considered carefully
dwarf gouramis - should be fine
kissing gouramis - bit too big for tank, though one could work with a considered community
silver gouramis - should be fine - nice fish
golden gouramis - should be fine but more aggressive than silvers
honey gouramis - should be fine
pearl gouramis - nice fish for tank

snake skin gouramis - nice fish for tank
cory doran cats - corydora cats yep any of the cory species are fine
spotted puffers - nope, need species tanks as they are nippy and their beaks do serious damage
catfish guppys - ..... not heard of these? Pics?
guppys - fine, but if you mix male and female you get tons of babies
pictus cats - fine good fish for the tank

congo tetras - nice fish for the tank

glo fish/mollies - - fine, but if you mix male and female you get tons of babies (didnt know you got glo mollies now

)
ballon mollies - fine, but if you mix male and female you get tons of babies
silver/black/orange mollies - fine, but if you mix male and female you get tons of babies
harlequins - good fish for tank
black phantom tetras - good fish for tank
sissor tail fish - should be okay
columbian red fin tetra - should be okay
golden danios - as above
peter elephant noise - little big for the tank though single specimen could work but if its your first tank I would avoid it as they need quite specialist care and are highly sensative to medicine which can be an issue if it arrises
zebra danios - good
silver dollars - nice fish but get quite big and although well suited for the tank would limit the rest of your stock
small clown loach - will grow into big clown loaches and eventually outgrow the tank
cherry barbs - good fish for tank
rainbow tetra - not heard of but assume it will be okay, unless it was a rainbow fish rather than tetra?
small/large neons - good fish, little delecate and need to be added to a mature tank of around 6 months old
black widows - good fish for tank
sun angels? - angel fish would be okay, tank is nice and tall so not too much of an issue
tin foil fish barbs - get too big and active, have a look in the members pics section at the 1000 gallon tank and see his adults
glo lights - good
rosey barbs - should be good but
pristella tetra - good
rainbow tetra - as above
green barbs - possibly green tiger barbs a bit nippy but manageable in large schools
dalmation mollies - - fine, but if you mix male and female you get tons of babies
serpae tetra - quite nippy would go for other tetras if you wanted them
red tail black sharkes - nice fish for tank but a more peaceful relative is the rainbow shark which has all red fins and would perhaps be a bit better
albino fish - need to narrow it down a bit all fish have albino strains
silver sharks - same as tinfoil barbs
red snake heads - these get really big about 4 feet, but there are other dwarf snakeheads available so perhaps sometimes to research
discus fish - need quite specialist care but perhaps possible in this tank but I wouldnt reccomend for first tank.
If it was my tank from that list I would do -
2 x Silver Gouramis
2 x Pearl Gouramis
8 x Congo Tetras
12 x Cherry Barbs
3 x Pictus Cats
So that gives you a good mix of mid sized fish with some bright red flashes darting around the tank.
Obviously though if you like other fish off your list better there are other stocking options for you to consider, hope thats helped
