  We present a detailed study of the massive star-forming region G35.2-0.74N
with ALMA 1.3 mm multi-configuration observations. At 0.2" (440 au) resolution,
the continuum emission reveals several dense cores along a filamentary
structure, consistent with previous ALMA 0.85 mm observations. At 0.03" (66 au)
resolution, we detect 22 compact sources, most of which are associated with the
filament. Four of the sources are associated with compact centimeter continuum
emission, and two of these are associated with H30{\alpha} recombination line
emission. The H30{\alpha} line kinematics show ordered motion of the ionized
gas, consistent with disk rotation and/or outflow expansion. We construct
models of photoionized regions to simultaneously fit the multi-wavelength
free-free fluxes and the H30{\alpha} total fluxes. The derived properties
suggest the presence of at least three massive young stars with nascent
hypercompact Hii regions. Two of these ionized regions are surrounded by a
large rotating structure that feeds two individual disks, revealed by dense gas
tracers, such as SO2, H2CO, and CH3OH. In particular, the SO2 emission
highlights two spiral structures in one of the disks and probes the
faster-rotating inner disks. The 12CO emission from the general region reveals
a complex outflow structure, with at least four outflows identified. The
remaining 18 compact sources are expected to be associated with lower-mass
protostars forming in the vicinity of the massive stars. We find potential
evidence for disk disruption due to dynamical interactions in the inner region
of this protocluster. The spatial distribution of the sources suggests a smooth
overall radial density gradient without subclustering, but with tentative
evidence of primordial mass segregation.
