There are ~3000 non-photosynthetic species of the ~350,000 members plant kingdom. Less than 1% are able to survive as heterotrophs without chlorophyll. These plants still have the basic plastid but they do not differentiate in to chloroplasts.
The Monotropa are classed as mycoheterotrophs. Mycoheterotrophic plants are “ectomycorrhizae" obtaining all their nutrients by parasitizing beneficial fungus, in particular the fungus that is used by the trees in Pinaceae, Fagaceae, & Betulaceae.
The Monotropa actually belong to the Heath family but are all root parasites.
In North America three plants are Allotropa virgata, Indian Pipe (Monotropa uniflora), & Pinedrops (Pterospora andromedea)
Another achlorophyllous group are the flowering parasitic Mistletoes.

All plants have chloroplasts. Some plants have chloroplasts without
chlorophyll. These plants get their energy from sources other than from
light. The best examples of these plants are parasitic plants that live
on other plants. Dodder (Cuscuta spp.) and broomrape (Orobanche spp.)
are common examples. You can find these plants in the woods and fields
of most temperate and tropical areas of the world and are easily
recognized as plants without green color--usually tannish with or
without some red pigmentation. These plants evolved from plants that
had chlorophyll and therefore, are considered plants. The
classification scheme is based on genetic lineages, not function.

yes, i think that all plants contian chloroplast. Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars, the raw material for energy and biomass production in all green plants and the animals that depend on them, directly or indirectly, for food. And if there is no chloroplast i don't understand how the plants will manufacture their food. so i think it is necessary for all plants to contain chloroplast..

I'm pretty sure they all have chloroplasts...that's what make them green.
We just go done with the plant cells in bio =)
But, just to make sure, I'd look it up on google.

crotons or plants with colored leaves do not have chloroplasts.they only have the coloring plastid-chromoplast.
eg:
Cascarilla (Croton eleuteria)
ocalia
Penteca
