Query: Candidate Milky Way Satellites in the Galactic Halo   Sloan Digital Sky Survey (SDSS) DR5 photometric data with $120^{\circ} <
\alpha < 270^{\circ}$, $25^{\circ} < \delta < 70^{\circ}$ are searched for new
Milky Way companions or substructures in the Galactic halo. Five candidates are
identified as overdensities of faint stellar sources that have color-magnitude
diagrams similar to those of known globular clusters or dwarf spheroidal
galaxies. The distance to each candidate is estimated by fitting suitable
stellar isochrones to the color-magnitude diagrams. Geometric properties and
absolute magnitudes are roughly measured and used to determine whether the
candidates are likely dwarf spheroidal galaxies, stellar clusters or tidal
debris. SDSSJ1000+5730 and SDSSJ1329+2841 are likely faint dwarf galaxy
candidates while SDSSJ0814+5105, SDSSJ0821+5608 and SDSSJ1058+2843 are likely
extremely faint globular clusters. Follow-up study is needed to confirm these
candidates.
