Greetings Sir..If 5th lord is placed in 8th House in its own sign (e.g. Singh lagna) then does it become bad for the significance of 5th House.

Secondly if in the above scenario Mars conjunct with Jupiter in 8th House, should we consider this conjunction as Benefic (being a conjunction of 5th and 9th lord) or should we considered as bad (being conjunction of Bhagyesh and 8th H lord)?

Kindly explain..
