Greetings, welcome to the Forums.
Asparagus densiflorus 'Myers'. The tuberous roots emerging from the ground in the last image are also from this species.
There are also four different bromeliads pictured. There are many species of bromeliad and many more hybrids and cultivar selections. Identification is more certain if they were blooming. The large red one is a spineless red pineapple (Ananas lucidus) or a hybrid of that. The one with silvery leaves looks similar to Aechmea fasciata. The one with red tips is Neoregelia spectabliis or a hybrid. The small green one in the corner might be another Neoregelia.
The plant in the clay pot is an Aloe, possibly Aloe vera or similar.
The yellow mushroom is a Flowerpot Parasol (Leucocoprinus birnbaumii), common in greenhouses, with houseplants, and outdoors in warm, humid climates.
