[Pratik Vyas]

Trello board create and team member already add i can share card only one member and not visible to other member it is possible? Please solve this issues.

Currently, Trello doesn't support per-card permissions—once someone has access to a board, they'll be able to see all cards on it and only board members can be added to cards. 

To give some context, when we created Trello we wanted to create a single shared perspective for all users and having different permissions for cards on a board would work against that concept, that all users can see that same and see the board at the same stage. Feel free to create different boards with different access permissions for the users in the meantime.

But Trello option attach members to a particular card in a list, what is that for?

@Pratik Vyas that's for keeping track of who is doing what

@Pratik Vyas creating a board to share with specific people then having each board linked to an "overview" card is a good way to keep track of lots of differently shared views:

If you only have some content that you want to hide, then you might try linking from the card to a Google doc shared only with some users.

It is possible to share/send single card or list from one board to other trello member in other board ?

@Marcin Horemski You can copy a card to another board, and copy a list then move it to another board.
