Magnetic Mirror and particle trap

[QuarkDecay]

Suppose we have two charged particles A and B released in the center of the Mirror (where the field is minimum). If A's velocity direction is parallel with the Magnetic field of the mirror and B's velocity is perpendicular with the field, then which one is going to get trapped, or escape, or neither?

I'm confused because the only example I could find was with only one particle moving with a random angle (different than 90 degrees or 0 degrees), and it separates its angle into one parallel and a perpedicular. When the particle heads towards the edges where the fiels is strong, the perpendicular component increases while the parallel descreases.
But I don't know how this could apply for two separate particles.

That's easy. Assuming that the particles are non-interacting, you can put them in separate bottles and see what each does in its own environment. What (I think) you are asking is what happens when a particle has a velocity that is (a) exactly perpendicular to the symmetry axis or (b) exactly along the symmetry axis. Is that your question?
