1. French, definitely. English was highly influenced by French during the Norman Conquest of England.
Like Spanish, French is a romance language and directly descended from Vulgar Latin. 2. German.It's a Germanic language like English.
German is one of the most inflected European languages, and Modern English is one of the least inflected European languages. However, you should be able to leverage on your knowledge of Spanish, which is a moderately inflected language.
Any latin based language will be familiar to you. -French -Portuguese -italian those would probably be the easiest for you to learn based on your previous knowledge.
