I think TDS u/s 194 I for rent will be deducted if payment exceeds exempn lt.

As per me if a consolidated bill has been raised for all, then Tds u/s 194C would be deducted on whole of the amount. In case individual bills has been raised, then Tds u/s 194C would be deducted on Rent paid for hall & DJ only.  

TDS u/s 194C ,as suggested ,doesnt make sense for full bill.To the extent that payment is for rented space(as you said its a party),it will be TDS for rent(see definition of rent u/s 194 I.
      TDS u/s 194C is relevant only for catering part -if any.
