Those are all excerpt from various Marcel Duchamp works
Here's a bad translation of them:

Inceste ou passion de famille, à coups trop tirés.
Incest or family passion, at blows too drawn the joke is that "à coup trop tirés" sounds like "à couteaux tirés"(at daggers drawn)
Rrose Sélavy trouve qu'un incesticide doit coucher avec sa mère avant de la tuer; les punaises sont de rigueur.
Rrose Sélavy finds that an incesticide must lay with his mother before killing her; bedbugs are required

Opalin; ô ma laine !
Opalin; oh my wool!
Un mot de reine; des maux de reins.
A queen's word; kidney pains.

Question d'hygiène intime, faut-il mettre la moelle de l'épée dans le poil de l'aimée ?
About intimate hygiene: shall we put the marrow of the sword inside the hair of the loved one? I think that this one is based on "poil" (body hair) sounding like "poêle" (stove)?
