The corn plant is Dracaena fragrans. 'Massangeana' is only a cultivar name, not a distinct species.

Bit hard to tell the genus and species of the palms from those photos. The fan palm looks to be a Washingtonia, but can't say which.

The Dracaena is D. fragrans as has already been said.

The "Philodendron" looks to be a very poorly grown Philodendron bipinnatifidum which recently got renamed Thaumatophyllum bipinnatifidum.
