Answer 1

It's hard to tell. Keep an eye in it and if more show up you probably have Ick. Your local aquarium shop will have meds for that. Ask them what would be best.

Find an aquarium shop that specializes in fish, not petco, petsmart, etc.

Ick is usually caused by stress. With this many fish you should have at least a 10 gallon tank. Take a sample of the water to the aquarium shop and they can test it for you, or you could purchase a test kit.

Answer 2

just raise your heat in the tank to mid 80's and add aquarium salt. Make sure to do an 80% water change.
