I'm afraid they're going to stay a mystery until you find a better camera!
No offense but ID-ing a pen is all about the details and some of those details require good light, strong magnification, and sharp focus; three things lacking in each of your shots. The details needed are usually on the clip, the nib and occasionally stamped or engraved on the barrel, so you have to position the pens such that those areas are pointing toward your lens (don't let them roll over on their side) while your light source falls directly onto the area you're trying to focus on.
That said, photo number Three either is, or is trying to be, one of Parker's better know shrouded nib models (most likely a Parker '51' or it's lowly step cousin, the Parker 21. There were plenty of copies and knock-off versions made in Europe, so without a better photo, we can't be positive. I would suggest you do some Googling--Parker 51 info is plentiful on the web--and see what you turn up.
