Ok for ich you want to turn up the heat in the tank. This speeds up the life cycle so it will get worse before it gets better. You can only kill ich once it is no longer on the fish so turning up the heat makes that happen faster. You'll want to turn up the temp to 84 or so. You can add a bubbler in the tank to help with the oxygen in the water.
Next you will want to add either aquarium salt or table salt depending on what you have laying around. The general rule is 1 teaspoon per gallon. If you have fish that may not be salt tolerant you can try 1 tablespoon per 5 gallons. Devolve the salt in a cup and add is SLOWLY. I would add a little of the salt mixture every hour until it's all in. Then just wait it out. Once the ich is no longer on the fish you will want to continue treatment for at least a week. 2 weeks is better.
If you do a water change remember to add some salt back to the water.
