I think #7 might be Euterpe (music)-- according to Wikipedia, Euterpe can be associated with a double flute (Aulos)... which looks kinda like the thing #7 is holding. At any rate, it isn't a compasss-- it can't bend or adjust to different angles (unless you're saying the pointy wandlike bit does? Hmm...). Although it doesn't look much like a musical instrument; perhaps she is the Muse of Plumbing?
Then #1 would be Erato (lyric poetry, associated with the lyre or cithara)--which would mean Erato and Euterpe have similar hairstyles and dress colors (both green, with... um.. roller-curls... and then Euterpe has the marching-band hat). Dunno; since Comedy and Tragedy have a similar black-and-white color scheme and hair styles, as well as Mime/Chorals and Dance having a similar pink-based color scheme, it makes sense to me that lyric poetry and music would end up similarly attired and coiffed. Then #2 would be Urania, of course, since she has the globe, and is dressed in sky-related blue shades. Color-scheme wise, you could then argue she matches with Clio (#3) and her purpley-blue dress... and then Calliope is on her own, with wings and gold and a totally different hairstyle.
Still no clue about the chain or urn on wheels.
Ok, I think I am officially overthinking this. ;-)
