Off by a few orders of magnitude. The minimum mass for a red dwarf is around 80 Jovian masses. That is the minimum to start the p-p fusion chain. For brown dwarves of 13 to 80 Jovian masses, one might find deuterium burning or lithium burning, but that does not last long. The energy currently given off by Jupiter is largely due to gravitational contraction and isotope decay.
No. Read the data. Jupiter would have to be much more massive then it is to be a star.
