amniotic sac
Yes, the amniotic fluid is released when the fetus is delivered. During labor, the amniotic sac often ruptures, commonly referred to as "water breaking," which allows the fluid to leak out. However, some amniotic fluid may still be present and is expelled during the delivery process. After the baby is born, any remaining fluid in the amniotic sac typically drains out as well.
The amniotic sac begins forming about 12 days after conception - the blastocyst becomes an embryo with three separate layers that will become the baby, the umbilical cord and the amniotic sac. This corresponds with implantation and hCG beginning to rise.
The amniotic sac can typically be visualized on an ultrasound as early as 4-5 weeks of pregnancy. However, it may be more consistently seen around 5-6 weeks.
Grasshoppers do not have an amniotic sac. Animals with amniotic sacs are mammals and birds that have a sac for the fetus to grow and gain nourishment from.

It can be either. Sometimes they are in their own individual sac, and in other instances they share one amniotic sac.
