Mr. Ramesh
Please perform Rudrabhishekam in the names of your daughters as Saturn is delaying their marriages. In your case 5th cusp (mantra stana) sub lord is Mars signifying 5th house and 11th house (fulfilment of desires and success). Moon is in 5th house. So Mars and Moon are the signficators of Parvathi mata. So rudrabhishekam to Lord Siva will help you. Mars is for energy and Moon for Parvati, Durga maa also can be appeased.
Good Luck
