Are my language tags correct?

Hello,

I have a Spanish website for Spanish speaking people es.example.com. I also have example.com for all English speaking people across the world.

I want that users who go to google.es and search in English get our example.com site and others who search in Spanish on google.es get the Spanish site.

Should the tags be like this:

Or should we also have this tag aswell to specify? Otherwise we might only show the es.domain even for english queris? :

Both the hreflang looks correct if your site is targeting only :

1. Spanish speaking users in Spain (hreflang="es-ES")
2. English speaking users in Spain (hreflang="en-ES"

If you are targeting English speaking users no matter the country, then you should use the hreflang="en" and not "en-ES".

You can create an hreflang with codes "en-es", because "es" also is the iso code of Spain as country, so the hreflang "en-es" is English in Spain (albeit would be better writing en-ES, but Google is not caps sensitive from what I know).

Second... you don't need to use the hreflang in every page, only in the ones that really need it.

For instance, if a page is canonicalized to another, the best way to avoid potential hreflang implementation mistakes (for instance, for not using the canonical URLs in the hreflang annotations) is not implementing it at all... because for its same canonicalized nature.

Hi there!

Just to confirm (it was implied by the Google.es comment but international targeting was never specified) - are you looking to target Spanish speakers in Spain only? Or are you attempting to target Spanish speakers worldwide?

If you are looking to target Spanish speaks in Spain only, then yes, this would be correct.

If you are looking to target Spanish speakers globally, you would want the tag to be:

Hello!

yeap, those are correct. 
And no, you should not create a hreflang tag with es-en. Remember that those tags must be in all pages, and have the self referential tag.
