"deep water" quandry

[hobogato]

got these pieces a couple of days ago and wanted to see what you all thought of my id guesses:

1. A. jacquelineae, A. turaki, or A. echinata

2. A. turaki or A. echinata

3. A. elegans or A. caroliniana

4. A. suharsonoi

am i right on any of them, and why or why not please.

thanks in advance

i'd say
turaki for 1
jacquelinea for 2
3 needs to grow out but id say those you mentioned, plus maybe lokani?

4, likely suharsonoi, but a size comparison would help, it might be caroliniana
