Hi. What is this plant called and should the plant inside be growing? What do I do about the yello?

It appears to be one of the many types of yucca! The yellowing can be normal, but it may mean that you need to repot it into a slightly larger container. The thing in the center is a flower. You can leave it until it fades, then cut it where it comes out of the plant.
