Which wayland-ivi, weston and wayland version are you using ? 

Can you send me a minimum example source code which reproduces these issues ?

Best regards

> 1)      We are unable to select the opacity values of layer using this API

> 3)      How can the composition be achieved in multiple layers (using buffer's
> alpha value only or Surface/Layer Opacity also is effective)?.
> 4)      We are unable to select between multiple LCD's. This
