pictures are REALLY blurry, but yea should work
pretty much you will see a flat part in the LED solder the 2 together the big piece is negative, and goes to the negative terminal.
then I'd get 2 resistors, and solder one to each of the other prongs left. Then solder the other end of the resistors together, and hook it to the positive terminal on the battery
Drew a fast picture IMO resistors should be something between 100-1k ohms so they don't fry(just make sure they match). LEDs in parallel will work for a while without a resistor, but I don't recommend it. I've used LEDs without a resistor in parallel and they have lasted anywhere from 20 mins to 10 months non stop use before dying. But remember any damage done will just keep accumulating
