As far as I know, there is no way you can take spanish text from a PDF and convert it to an english Word document using Acrobat. It is not capable of translating.
What you can do is to open the PDF, go to File>Save as and there is the option of saving all the text in RTF format. This will be saved in the spanish characters used. This RTF file can be opened in Word, from where any translation will have to be done (there may be software that can do this, but I don't know of any).
The layout of the document will be lost as no images will come with the RTF file. However, you can save images separately by using the File>Export>Extract Images As and you are given the options of PNG, JPG or TIF. These would have to be inserted separately into the Word doc if you wanted to recreate the original layout (as far as Word's capabilities can manage).
But the font is almost irrelevant as you will need to translate the spanish to engish first (which will probably require different fonts) and then format the result in whatever font you want.
Sorry I can't be of more help.
