Picked these up at Trader Joes. Can I get some help with ID?
 

Imgur: The magic of the Internet

All three are simply labeled as "exotic orchid" (even on their inner hang tags and bottom stickers). The two orange ones are fragrant, the white blooms are not. The one with white flowers is also sending up an additional new spike.

The large orange and the white both have bulbs at the bottom. The large orange seems like some type of oncidium. The small orange has so much of a little forest it's hard to tell much of anything.

From the flowers they are both oncidium types, probably hybrids.
Nice find!

They are all Oncidium alliance intergeneric hybrids and will all do well in about the same growing conditions. Reasonably warm but not hot, bright light, frequent watering while growing but slightly drier in winter.

These are all likely to be mass produced clones so there's a reasonable chance that someone will be able to make pretty accurate recommendations / guesses. You could probably poke around in a Google image search and find close enough IDs on them.

The red/orange toned hybrids are probably Wilsonara/Colmanara (or hybrids that were formerly called Wilsonara) and the paler one is probably Beallara/Aliceara (or similar or formerly Beallara).

I have thoughts but I like to see what the experts say first (it builds my confidence). They are all in the Oncidium tribe. The white one might be a Beallara Tahoma Glacier. You'll never know for sure

The ID on the white looks spot on. The only thing it's missing is the fragrance (supposed to have a bit of a spicy fragrance). I'll have a go at it a bit later and see if I can pick it up on any of them.

Oncidium twinkle for the orange with the full spray of tiny flowers...

I've been suggested Oncidium sharry baby for the red, but I feel like the spray is too sparse for that to be quite correct.

It's to orange for Sharry Baby and that's not a twinkle. The whole plant looks too big, as do the flowers.

On the large red-- Wilsonara Hilo Firecracker

Agreed with this one.

On the big white one = I would look up Beallara Tahoma Glacier and see if you think it matches..

Nice haul! I have no idea on the IDs, but I have one like the white one purchased at Trader Joe's about 3 years ago now. It's done great outside in bright shade (it purples and burns with even limited morning sun exposure). I only bring it in on nights when frost is in the forecast.
