I don't scatter palms, they are placed manually. Hair was on the palm but it will always stay in it's original position even if I move linked object(palm) away.

Have you tried to make hair real? There is a way to make a mesh object from particles. Check the blender manual. Work woth a copy of the scene because it is a tricky way to go.
Do not forget to make mesh object using one user only (should be in the vertex menu, some button in the menu line, I mean the menu you can define e.g. vertex groups). If you do not make single user, you may get a real mess.

You can make any material transparent, it is a general material attribute and it is not related to glass (it is just the % of rays that will pass trough). For instance, you may want to use a 50% transparent mirror.

Ok, I think you need to use OBJECT_ID_MASK AOV to get the mask of "glass" object, once you have the mask you can use photoshop/gimp/Blender for any type of compositing you may need

OBJECT_ID_MASK AOV isn't exactly the transparency but they are values between 0.0 and 1.0 so it can be scaled to any level of transparency you need (during post-processing/compositing).
