  In order to solve problem of spacetime singularity in theoretical physics,
researchers proposed the regular black holes (BH). The generalized black-bounce
(GBB) spacetime, as a unified treatment of distinct kinds of geometries in the
framework of general relativity (e.g. regular BH and wormholes), has been
extensively studied. Firstly, we derive to give the explicit forms of
Lagrangian for a nonlinear electromagnetic field and potential for a
non-canonical phantom field in the action of gravitational system corresponding
to GBB solution. Secondly, this paper computes the radius of the innermost
stable circular orbit (ISCO) and the stable circular orbit region for different
types of celestial bodies in GBB spacetime. The research suggests that
traversable wormholes may have two ISCOs or one ISCO depending on the throat's
scale, whereas regular BH and extremal BH possess only one ISCO. Thirdly,
quasi-periodic oscillations (QPOs) have been found to be a reliable tool for
testing gravitational theories. Therefore, we compute the radial and azimuthal
epicyclic angular frequencies of particles oscillating on stable circular
orbits around various celestial bodies and compare them with the oscillation
frequency properties of schwarzschild BH. Moreover, due to the limited amount
of research on the high-frequency quasi-periodic oscillations (HFQPOs)
phenomenon and its generation mechanisms around particles near wormholes using
observational data, this paper aims to study theoretical models that can
simultaneously describe both BH and wormholes by fitting observational data.
Using resonance models and associated frequency ratios, we are able to locate
the resonances of different celestial bodies within the GBB spacetime.
