Are there films in Spanish or subtitled in Spanish?

Yes, they have several showings every day

And

If there is in Spanish and there are also subtitles. You can see the options online and also choose and reserve the specific seats.

Of everything

I recommend you download the Cinemark application, there you will find schedules and details about the film that indicate if they have subtitles or in Spanish

Yes

Yes there are but they are for almost 4 or something like that
