A little puzzle

[FluffyMcDeath]

1 : MKL

2 : pent diamond or plus pent

3 : RUST

4 : circ

5 : diamond plus

[edit]

I see that between you, you've already covered both variants of Q2.

but why RSUT? I disagree. I think I see what you were thinking based on the horizontal path, but check the vertical.

Yes. RSUT.
I guess I had a dyslexic moment with the diamond operator and it pooched my results. (That and an insane preference for real words over nonsense sequences seemed to have biased me).
