Sometimes CubeSats will launch as ride-alongs on the rocket itself (it's more common on rockets not already going to the ISS) and others are designed to be launched from the ISS itself depending on how they're being paid for. In either case they'll wind up in the roughly 51 degree inclination of the ISS.

They can't really capture satellites because very few actually orbit at that level it's mostly the kind of short term cube sats that they launch out not larger satellites. Those live in higher orbits so getting to them to fix is not a small task. Another big hurdle is the orbital inclination changing that is extremely expensive to do, basically everything is placed into it's final orbital inclination at launch because of the fuel requirements to change it once you're in orbit. It's why the ISS is at such a high inclination to begin with, so that it's easier to get to from Baikonur where Russia launches it's vehicles from.
