The aquarium is only 60 liters (15 gallons) and not suited to adequate numbers of the mentioned fish, and some (the molly) will outgrow this tank on its own.
Have you had these fish for a while? If recent, perhaps some can be returned to the store?
What hatchetfish species are the two? Some are slightly larger asnd more active and willnot fare well in this small a space. And I agree, the Betta must go, it is not a community fish and trouble is almost inevitable so best to work out the issues now before they develop.
Interesting, there was a near-identical thread a few weeks back, but I can't find it now...coincidental I guess.
