have you tried [mod edit; link to unreliable site removed]
That's a good site to use if you're unsure of the stocking of your tank.
I don't know anything about any of the fish you're planning on having. Only the corydoras.
Why is that site not on the banned list any more, where the name is blanked out? Current mods/admin?
This stocking calculator has flaws that convince inexperienced fishkeepers that certain fish are fine together when they usually are not and that it is acceptable to squash fish into insufficient sized tanks like "sardines."
Back to the OP stocking...
How hard is your water?
What are the tank dimensions of this 55 (US gallons?)?
I'm not sure that Swordtails are a good mix with Angelfish or Hatchets, the former enjoy a moderate-strong current and may spook the other two with their activity (both at feeding and generally). These fish need hard water, anything greater than ~gH 10 should be fine.
Can the tank contain >45cm of actual water depth? If not, Angelfish are not suitable. Also a "random duo" put together in a tank is dangerous, either by a bonded pair; a singleton; or a group of 6 to usually get a bonded pair and rehome the other 4.
Marble Hatchets can be a bit fragile and they are one of the smallest members of the type at ~3cm SL, while Angelfish will not be able to swallow them whole, I've lost count of the number of times I've seen Angels in fish stores giving pretty small fish grief.
