Answer 1

If you want to display double quotes inside double quotes, you have to escape them:

$> echo "today's \"program\""
today's "program"

You could also concatenate quoted strings:

$> echo 'today'"'"'s "program"'
today's "program"

Or just escape them all:

$> echo today\'s \"program\"
today's "program"

Answer 2

> echo 'Today'\''s "program"'
Today's "program"

Answer 3

Multiple possibilities:

> echo 'Today'"'"'s "program"'
Today's "program"
> echo Today"'"s '"program"'
Today's "program"
> echo Today\'s '"program"'
Today's "program"
> echo Today\'s \"program\"
Today's "program"

For the difference between these 3 kinds of escaping see for example this article.
