Block to build homepage

[kmk]

There is already multilanguage block or widget that let me place on a homepage as redirect?

I am unsure what you mean by "as redirect" - if you redirected visits to your homepage, then anything you embedded wouldn't show up to the end user.

To answer your first question, you would have to build it manually, i.e. doing something like this in a Pages custom block:

{{if \IPS\Member::loggedIn()->language()->short == 'en_US'}}
 English text
{{elseif \IPS\Member::loggedIn()->language()->short == 'de_DE'}}
 German text
{{else}}
 ...
{{endif}}
