Ooh, Ouch! All 3 are rather common and all are damaged. The 3 cent pinkish stamp is from the 1861 series, and were grilled at times. The 2 1 cent stamps are large banknotes, unsure exactly which one as there is not a lot of detail in the photo, but they are also damaged. These also can have grills.
You can find your stamps using the visual finder on this very helpful website.
