I think I understand what you mean.
You press play. A random sound plays among the 5 sounds you have.
Then Sound 3 plays, you have to click Card 3. If sound ends, you loose.
You do it like this:
Global Numbers variables:
S1 / P1 / S2 / P2, etc... to 0 each
You need to set tags in your "Play" sounds.
On S1 stops playing: if P1 = 0 then player loses. if P1 = 1 play next random sound and set P1 = 0.
On P1 clicked:
If S1 is playing: Set P1 to 1.
On P2 clicked:
If S2 is playing: Set P2 to 1.
etc...
