Hi thanulee,
There are a few plugins that I have not installed. I do not see the problem in those, but I need to mention it. Whenever possible, just the parts of a scene file which is able to reproduce the question content. Thank you.
I would change two things in your set up.
First, give every selection a unique name. (It should work even with the same name, but 11 object and four Hair objects, confused me))
Second, do not scale down to zero while hair is involved. Hair has no idea what to do when the polygon has a size of zero.
Please have a look at the files below.

File “…_01.c4d” works just fine, and “…02.c4d” does not at all. File 02 was scaled to zero.
If you need to some of the “actors” to disappear, use the Visibility options (Attribute Manager> Visible in Render) and animate those.

My best wishes for your production.
Cheers
