It is impossible to obtain more than one treasure at a time except under these cases:

-Guaranteed stage rewards, ie clear chapter catfood and crazed cats stages. Clearing the stage for the first time will give you the guaranteed crazed unit along with a small chance (guaranteed if radar enabled) random powerup.

-Time attack stages. If you managed to get gold on first run, you can obtain total of 5 guaranteed rewards + a random powerup (small chance/guaranteed with radar) + 30 catfood (if last stage of the chapter) for a total of 7 treasures at once then.

Otherwise if you got like only 2 or 3 of the score rewards, you still can try again later on to obtain the rest.
