you didn't let the tank completely cycle it sounds like. Also adding three fish at one time to a 4 gallon tank is a bad idea. I only add 3-4 at a time in my 210 gallon. Either you didnt cycle the tank properly or you spiked the ammonia by adding too many fish. Either way you learned you first Saltwater lesson. MOVE VERY SLOWLY. Nothing good happens fast but bad things do.

In a 4 gallon tank you might be able to safely put a single goby in it, 3 damsels are FAR too many for a tank that size. The smallest tank you want to put any type of damsel in is a 30g.

When you add fish you need to take a fair amount of time to acclimate the fish as they need to be acclimated to pH, salinity, and temperature. i usually take at least an hour to acclimate any new fish to my tank.

You also didn't give your tank time to cycle. New live rock will have a large amount of die off form organisms that died during shipping throwing tons of ammonia into the tank. It needs to be cured and then cycled before anything gets added to the tank.

Lastly, a small tank is a nightmare to keep healthy. I wouldn't even consider doing a tank smaller than 20g for a first salt water tank.

First off, you will absolutely need to return the damsels. Then I would highly suggest some more research at maintaining and starting a tank. You also really should research tank sizes for fish before adding them to a tank.
