Hello All, I am using DM6446 (TI DaVinci) customized board.

1. I am not able to understand meaning of NAND Sub system U boot commands, e.g. nand write, nand read, nand erase etc.

"write", "read", and "erase" are fairly straightforward English words. Is there some particular aspect you find confusing?

2. I want to use the NAND sub system U boot command in Linux (ARM side

of DM6446 core), is it possible ? may be some utiliy to export these commands

No. U-boot does not remain active once Linux boots.

or some paralle command which have similar functionality (such as writting on specific location of RAM (87000000) from nand(0X1000000)).?

See nandwrite in the mtd-utils package.
