Good Morning Suza. Nicely grown orchids, but the answer is once a NO ID nearly always a NO ID.

There are more than 9800 registered Dendrobium Hybrids.

A bit harder to guess at the possible numbers for the second hybrid. It is in the Oncidiinae Sub-Tribe of orchids and I have no idea of its ancestors.

Maybe ask Trader Joe where "he " gets his orchids.

Here are here the link to pics of Orchids exhibited in the Oncidiinae Sub Tribe Classes at a local orchid society to give you an idea of variation.

I am not sure about the hard cane Dendrobium. However the second one might be Degarmoara Winter Wonderland or something similar.

Clearly you are doing a good job with both!

I agree with both Arthur and Darlene. Both blooms and plants are lovely. Congrats on good culture!

Beautiful blooms :)

Thanks everyone! I find the NOIDs to be a fun challenge since I can't look up their culture, I just hope for the best. Clearly, these are doing just fine.

Poking around online, the 2nd plant looks a bit like Bllra Tahoma Glacier Sugar Sweet or as Darlene suggested Degarmoara Winter Wonderland. Curious if anyone has grown either of those?
