Are there stars that orbit perpendicular to the galactic plane?

In spiral galaxies, there is commonly a ‘galactic bulge’ of light. As most of us know, stars usually orbit around the plane, but is it possible for a large number of stars to orbit at (at least close to) a 90 degree angle relative to this? If so, how would that formation process have occurred?

Or am I overthinking it and the bulge is simply a result of the massive light output from the high density of stars?

Edit: just to clarify, I know that there are irregular galaxies that are composed of stars in a ‘cloud’ of sorts, like the Magellanic Clouds. I am referring to conventional spiral galaxies for this post.

Edit 2: by ‘large number’, I’m referring to a significant portion of the total number of stars. Maybe 0.1-1% of total stellar count or mass. Something along the lines of 0.1-10 million stars at least.

Sure, in the bulge or the stellar halo of spiral galaxies, the orbits are *basically* random, so you get orbits in every direction (some bulges resemble elliptical galaxies in some ways). Whether it counts as "a large number" is up to you.
