Sadly you can't. You have to sell items one at a time.
Farmville flowers last for 16 days from the time you placed it on your farm. After that it will droop and all you can do is delete or sell it for 0 coins. You can share your harvested flowers to your neighbors. It's also a good item to decorate your farm.

Hello ! I work for Zynga, the brand that first started FarmVille. If you do sell your wishing well, a bill will be sent to you, asking you to pay a fine of 50,00$. Since we accessed your account when you first started to play FarmVille, we know where you live and who you are.
Same way you sell any item. Go to the sell section, then select the item, and then state the quantity. The fish were kind of hard for me to find, but they are in the section "Extras", sub section "Junk"
Yes.
Well, that's probably not a popular item to sell right now. Maybe you could check in a week or so. It just depends on what's selling.
