the shrimp will absorb the water and it will turn to mush, fall apart and will be too soft.

Keep them in the refrigerator but not in water, just in a sealed container.
not solid frozen but a little frozen is ok although its easier for them to eat non frozen shrimp.
It might be. So much depends on the quality of the shrimp before it was frozen and how it has been handled since. You will have to make the decision yourself. If it isn't slimy, watery, or mushy and doesn't have any off-odors, it might be OK to use. In reality, it is getting towards the end of how long you should keep it.
no
yes because it is frozen and everything frozen weighs more then unfrozen.
One of the most cost efficient shrimp recipes is Shrimp Gumbo. It is made with rice, which is inexpensive, and can be made with frozen shrimp. Frozen shrimp are far less costly than fresh shrimp but are almost as delicious. The actual cost of the meal will vary according to where you live and what kind of grocery you shop at, as well as how many people you wish you serve. Another simple meal with frozen shrimp is battered and fried shrimp served with cocktail sauce. Again, the shrimp will be less expensive because they are frozen and the only other small expense will be the cocktail sauce.

Yes they can.
