Very hard to say, but whatever they are, the first is not healthy. To me, it looks like a Cattleya type. It seems to have a bud, so if it opens, post a pic. The medium looks quite wet, so try to dry it out a bit. Use some Safer's soap on it to try to keep the bugs at bay, if there are any. The second one, I don't know. Where did you get the plants? Who told you they were from Sri Lanka?
The plant is too small and sick to see the pseudobulbs in this photo. The leaves do look like Cattleya-type leaves. I've had plants of my own that have looked like this, so I will say it is something in the Cattleya alliance. The 'fruit' is a seedpod (orchid seedpods are usually not called fruits). I had said earlier that it was a bud, but looking again, it looks more like a seedpod. If so, the plant will be using it's energy to produce seed instead of making a healthier plant.
The term seedpod is bad terminology, seed-capsule, green capsule, dry capsule, some may use green pod, dry pod.

I have spent 41 years of my life as a student of orchidology, even with a PhD I still tell every one I am just a student. The plant is in stress mode and the photo is weak in quality, as for the seed capsule/ fruit that’s obvious.
So very true, Kevind76 there is a lot of bad and incorrect information out there. For people who wish to learn more about orchids, and learn correctly it is difficult at best.
Really just to many show-boaters and so called experts…..
The third photo is most likely an Oberonia species. There are 15 recorded species of Oberonia in Sri Lanka and without a photo of the flower (which is tiny) it's virtually impossible to exactly identify which species it is.
The other two photos are not clear enough to see. If you have better photos I might be able to help.
Btw the first photo, if it is actually from Sri Lanka, is most certainly not a cattleya or related genus as they come from central and south America and there are no cattleyas native to Sri Lanka or Asia.
The second photo is most likely a bulbophyllum species. But the photo makes it difficult to identify it correctly. It could even be a dendrobium diodon or an Eria species. If you can post very clear hi-res photos it might be easier to exactly identify the genus. If it is a bulbophyllum, without photos of the flowers it will be tough to say exactly which species it is.
