We present two independent , homogeneous , global analyses of the transit lightcurves , radial velocities and spectroscopy of Kepler-4b , Kepler-5b , Kepler-6b , Kepler-7b and Kepler-8b , with numerous differences over the previous methods . These include : i ) improved decorrelated parameter fitting set used , ii ) new limb darkening coefficients , iii ) time stamps modified to BJD for consistency with RV data , iv ) two different methods for compensating for the long integration time of Kepler LC data , v ) best-fit secondary eclipse depths and excluded upper limits , vi ) fitted mid-transit times , durations , depths and baseline fluxes for individual transits . We make several determinations not found in the discovery papers : i ) We detect a secondary eclipse for Kepler-7b of depth ( 47 \pm 14 ) ppm and statistical significance 3.5- \sigma . We conclude reflected light is a much more plausible origin than thermal emission and determine a geometric albedo of A _ { g } = ( 0.38 \pm 0.12 ) . ii ) We find that an eccentric orbit model for the Neptune-mass planet Kepler-4b is detected at the 2- \sigma level with e = ( 0.25 \pm 0.12 ) . If confirmed , this would place Kepler-4b in a similar category as GJ 436b and HAT-P-11b as an eccentric , Neptune-mass planet . iii ) We find weak evidence for a secondary eclipse in Kepler-5b of 2- \sigma significance and depth ( 26 \pm 17 ) ppm . The most plausible explanation is reflected light caused by a planet of geometric albedo A _ { g } = ( 0.15 \pm 0.10 ) . iv ) A 2.6- \sigma peak in Kepler-6b TTV periodogram is detected and is not easily explained as an aliased frequency . We find that mean-motion resonant perturbers , non-resonant perturbers and a companion extrasolar moon all provide inadequate explanations for this signal and the most likely source is stellar rotation . v ) We find different impact parameters relative to the discovery papers in most cases , but generally self-consistent when compared to the two methods employed here . vi ) We constrain the presence of mean motion resonant planets for all five planets through an analysis of the mid-transit times . vii ) We constrain the presence of extrasolar moons for all five planets . viii ) We constrain the presence of Trojans for all five planets .
