Being a troglodyte, I miss all the cultural references here. What is the challenging quote (who is that guy -- he's in some Medieval/Renaissance show, but there are so many of them)?
The first picture has two long word clusters, apparently nouns though maybe verbs. I assume they are meant to be sentences with, say, a 'li' after 'jan' and an 'e' before 'ni'. The second is maybe an imperative, lacking initial 'o'? The second note says "no" to the latter, making it an infinitive with 'ken' (which can, however, be a transitive verb "to empower"; it just doesn't make much sense here).
So the second picture works fine, though I still don't see the point of the 'kin'.
Third picture. "A different language? I don't think" presumably with "so" 'e ni'.
Cat: I assume the picture stands in for the subject here (interesting)
Scream: missing 'o' or 'li'?
'Crat: Missing 'li'? "forgets"?
Brat: 'nimi 'pi''. (names are adjectives).
