Applying two coats of stain to your hardwood floors will result in darker tones; however, this may be necessary to obtain the stain tones you wish for.
There are several factors that effect the reapplication of wood stain. The type of wood, if it's a close grained / pored hard wood and you're using a spirit based stain, give it about 10 min's between coats to allow the stain to sink in and the spirits to evaporate. Reapply the next coat doing the same etc Solvent stains are much the same. Soft wood or ply types can be re coated in about 1 minute but don't apply too much stain at a time. It also depends how you apply the stain, either a paint brush or a wad of lint free cotton type material so don't apply too much as above.
