There can be as many as 5 or 6 planets in the same house but such is a rare occurrence. These are in fact the most difficult horoscopes to interpret. Care must be taken in determining how the planets affect each other. There could be a Yoga or a planetary combination) forming due to the conjunction but if a malefic planet is operational in the same house, the Yoga may not fructify for the native. On the other hand, when multiple weak or malefic planets get together in a house, presence of a benefic could balance the situation. Nevertheless, its power would be low due to malefic influence so the horoscope can only be considered average.
Conjunction of multiple planets in one house indicates the focus area of your life - the house where most of the planets are placed. Nevertheless, there could be some misbalance in the personality of the native due to the strong pull of a single house. The lord of house where conjunction of planets takes place is also under the spotlight. If it is positioned well, it casts a benefic influence upon the native. It tends to make other planets strong too. However, if it is weakly posited or under malefic influence, it may only deem negative results and may worsen the situation.
