Cipher competition (all in one place)

As some of you might have seen I am holding a cipher competition last week I posted a cipher each day after the week only one person decoded all the ciphers, however the competition is still open but instead of you searching Facebook for them they will be below making it easier to find and decode.

Anyone who decode these will appear in my comic (Wednesday 4th may)

If your struggling to decode them there is this website that may make it easier
