Hi gang, bit of an urgent one this.

I wonder if anyone here might be able to assist me in identifying the fonts that make up the text fields on the below graphic?

There are 14 fields in total, but I am sure the 14 are comprised of no more than 3 fonts ie: I think most of them are variants of Helvetica (possibly?) although I am not sure which variants etc, this is where I need the help.

If you guys can maybe list the identities according to the numbers in the graphic, that would be superb.

Cheers Claude, any chance you know what Number 4 is too? I have been told it might be a Serpentine font of some sort, but could do with a specific I.D it someone is able?
