The first plant appears to be Masdevallia picturata; the second an Oncidium species. If you are living in Yumba
Valle de Caucana, I suggest you consider contacting the
Asociacion Vallecaucana de Orquideologia
BIENVENIDOS .:::. SOMOS LA ASOCIACION VALLECAUCANA DE ORQUIDEOLOGIA ::. Their international orchid show is being held this weekend at the Orquideorama Enrique Perez Arbeldez, Av. 2 Norte No. 48-10, Barrio la Merced in Cali. Also see if you can find the 6 volume set of Orquideas Nativas de Colombia published in 1991 by Editorial Colina.
