Since your LEDs have different brightnesses then their currents are probably different. The brightest ones might burn out if you use a 27 ohm resistor.
Since your LEDs are soldered in parallel then you cannot measure their individual currents.
Cheap LEDs are made to look bright by making their case focus them in a narrow angle.
