Any ideas what they are?

Reset them all, take it for a drive and see which ones come back as that seems a lot to me to happen all at once, the ones that come back can then be rectified. Could be left on from previous repairs.

On the last two look for split vacuum pipes under the shield at the front of the engine close to the dip stick.
