Divergent Universes
It has been mentioned by Needlemouse that there are more universes in which people have been 'encaged'. This, paired with additional info granted by myself, leaves us with these universes:
 * Tails Encaged
 * Knuckles Encaged
 * Amy Encaged
 * Shadow Encaged
 * Silver Encaged
 * Blaze Encaged
 * And possibly more.

Additional Information
Amy Encaged is said to be very important, because curiously, Infinite could not harm Amy during her stay in The Cage, but despite this, Amy was not able to get through to him. Infinite killed Amy out of frustration and erased the universe.

The reason Infinite was 'encaging' people was to learn more about them, mostly how to break them down. He did not encage those who he deemed unable to pose a threat to him. This would imply that he has encountered versions of each 'encaged' character that have posed a threat to him in the past.
