You've got a pretty paphiopedilum concolor, but the exact name of your plant would be impossible to tell.

For the second one, I'm at a loss; you're probably going to have to wait for flowers. Or at least until it's a more mature plant.

I agree, Paphiopedilum concolor.

The second plant is impossible.....something in the Vandaceous group of plants.

Thank you dannie and arthur for your helps, i appreciate it.
