Just to help others who might have the same headache, let's update this thread with the information that I found for the second orchid.
The second one:
is the Oncidium (ornithorhyncum) Sharry Baby 'Yellow Flash' hybrid orchid.
As for the 1st one:
I have found that probably is the Beallara 'Peggy Ruth Carpenter'.
