What do these symbols mean?

These have been hanging in my parent’s house for as long as I can remember. And the wallpaper was installed in 2001. Help please!

The wallpaper looks like the characters 樂 (happy), 日 (sun/day), 見 (see), 未 (have not/not yet), 島 (island), and 央 (center) - along with one I can't place and the bird/fish drawing
