  The census of the solar neighborhood is almost complete for stars and
becoming more complete in the brown dwarf regime. Spectroscopic, photometric
and kinematic characterization of nearby objects helps us to understand the
local mass function, the binary fraction, and provides new targets for
sensitive planet searches. We aim to derive spectral types and
spectro-photometric distances of a sample of new high proper motion sources
found with the WISE satellite, and obtain parallaxes for those objects that
fall within the area observed by the Vista Variables in the V\'ia L\'actea
survey (VVV). We used low resolution spectroscopy and template fitting to
derive spectral types, multiwavelength photometry to characterize the companion
candidates and obtain photometric distances. Multi-epoch imaging from the VVV
survey was used to measure the parallaxes and proper motions for three sources.
We confirm a new T2 brown dwarf within $\sim$15 pc. We derived optical spectral
types for twenty four sources, mostly M dwarfs within 50 pc. We addressed the
wide binary nature of sixteen objects found by the WISE mission and previously
known high proper motion sources. Six of these are probably members of wide
binaries, two of those are new, and present evidence against the physical
binary nature of two candidate binary stars found in the literature, and eight
that we selected as possible binary systems. We discuss a likely microlensing
event produced by a nearby low mass star and a galaxy, that is to occur in the
following five years.
