1, 3, and 4 for me. 5 and 6 are awful- 6 is ridiculously tacky, and I absolutely hate in your face branding like 5. It's a way of saying, "I don't have taste, so I'm showing you how much money I spent on this instead."
1 is a classic wool tie, 3 is a classic and useful pattern, and 3 (again, providing it's not that shiny in real life) is a fun stripe, though perhaps a tad wide.
However, I wouldn't try to have them narrowed. Tiecrafters gets good reviews on here, so if you were to insist on it, I would go to them, but I wouldn't trust a local alterations shop or dry cleaner- ties are tricky things to mess with.
1 is ok. 3 is a maybe depending on the color in real life. As Vinny said, 5 is ok if dots. Those are wearable for a change of pace or to try something different, but not something I would wear or recommend for an important occasion. For $15-30, you can buy nicer ties here or on ebay.
