  Atom interferometry with high visibility is of high demand for precision
measurements. Here, a parallel multicomponent interferometer is achieved by
preparing a spin-$2$ Bose-Einstein condensate of $^{87}$Rb atoms confined in a
hybrid magneto-optical trap. After the preparation of a spinor Bose-Einstein
condensate with spin degrees of freedom entangled, we observe four spatial
interference patterns in each run of measurements corresponding to four
hyperfine states we mainly populate in the experiment. The atomic populations
in different Zeeman sublevels are made controllably using magnetic-field-pulse
induced Majorana transitions. The spatial separation of atom cloud in different
hyperfine states is reached by Stern-Gerlach momentum splitting. The high
visibility of the interference fringes is reached by designing a proper overlap
of the interfering wave packets. Due to uncontrollable phase accumulation in
Majorana transitions, the phase of each individual spin is found to be
subjected to unreproducible shift in multiple experimental runs. However, the
relative phase across different spins is stable, paving a way towards
noise-resilient multicomponent parallel interferometers.
