have you fish less cycled the tank before adding the fish. by this i mean added a form of ammonia.
if not is it a white cloudiness but you can not see any particles. in which case its a bacteria bloom. if your water testing fine, let it run its course. it will clear on its own.
if water test is bad, depending on results you may need to do a water change.

The problem is that your tank isn't 'cycled'. That means it doesn't have a colony of good bacteria living in the filter. The bacteria eat the ammonia produced by the fish and turn it into less toxic substances; first nitrite, which is also toxic, and then nitrate, which is only toxic at very high levels, and which we keep low with water changes, in a cycled tank.
Just running a tank does not cycle it; you need a source of ammonia to do that.
You will need to get test kits for ammonia and nitrite, so you can monitor the levels and keep them low with water changes.
The cloudy water is a bacterial bloom (not the same sort of bacteria we want in our filters, unfortunately!). It will clear up on its own, but you will be doing water changes anyway, to keep your fish safe while your filter cycles.

If you can keep both ammonia and nitrite under 0.25ppm, at all times, yes, they should be alright, although there is always a risk involved in fish-in cycles.
Oh, and we would very strongly recommend you buy decent (liquid or tablet based) get kits of your own, rather than relying on the shop or on the paper 'dip strip' kind. The paper tests aren't very accurate, and you may need/want to test the water when the shops are shut!

how big is the tank? the cory numbers need uping eventually.
Is there any way you can take some fish back? The corys & mollies need a bigger tank.
