Assume they collide and deflect at different concentric orbital angles (assume no friction, and assume any arbitrary initial velocities)

Yes, given an infinite time period.

It's a strange event you describe, where the marbles may be made to do anything "inside a 10 foot hollow sphere", and, they simply "collide and deflect..." in the customary manner of same. Here's why your question is the very epitome of poor inquiry: it abstracts from nature in a vulgar attempt to improve it. From nowhere the distanced observer appears, happens upon phenomena and has so little imagination, wonders whether the already questionable event will happen again. Incredibly vapid! Well, I suppose if the tinkerers must get a tighter grip on it, they must. LOL.

You could fit about 14 million marbles inside that big sphere. After the 2 marbles collide, and after a long enough time, the 2 marbles are in practically random locations. So they have about 1 chance in 14 million of colliding again, each time they move 1 marble diameter. If they are each 1/2-inch in diameter, and move at 10 inches per second, then that's 40 marble diameters per second combined speed.
14,000,000 / 40 = 350,000 seconds between collisions, on average = 4 days, 1 hour, 13 minutes. More or less.
Between collisions, they will each hit the wall over 40,000 times; that should be enough to satisfy the "practically random" condition.

Yes, with no outside forces changing the orbit, they will collide again.
what you will find is that the marbles will go to the center of the largest out side part of the sphere, by means of centripetal force.
But planets and there orbits are totally different, gravity controls their orbits, where spinning marbles are controlled by centripetal force.

Yes. Something caused them to collide. Provided the conditions are identical, they will collide again: albeit may take more time.

Eventually.

if non of the marbles stop moving they will collide again

The odds are overwhelming that they will collide.

Yes, cause they have the same point of origin.
