When moving mouse over register link it should show mysite.com/become-member/
But it shows mysite.com/wp-login.php?action=register

I also tried to enter this in URL bar mysite.com/become-member/ and get error.

I didn't add any other rewritten urls they where already there.

You're going to have to change the "register" link yourself. Mod_rewrite can't do this for you.

I also tried to enter this in URL bar mysite.com/become-member/ and get error.

What kind of error? The same 404 not found?

I found this in wp-signup

Code:

if ( !is_multisite() ) {
	wp_redirect( get_option( 'siteurl' ) . "/wp-login.php?action=register" );
	die();
}

if ( !is_main_site() ) {
	wp_redirect( network_home_url( 'wp-signup.php' ) );
	die();

What should I add here?
