cypher puzzle

I am new to this but wondered if anyone has seen it before and can explain how they got the answers:

I have the answers up to level 18 but still don't understand how people figured them out

 

I realise that the pic in the 1st level looks a bit dodgy but it is not what you may think it is and the solution to that one is on the same page.

I completely fail to see any logical answer for the first question, so I'm no help whatsoever (can you whisper it to me please?)

I can't even see the question anywhere on the page, so I can't even begin to try and work anything out - LOL!

Me neither, I know I am old but did n't think I was that thick.
