So any more than four is "too many to count"? lol
As for me, it depends on how you define "speak"... and how you define "language".
My native language is English, I'm fluent in Esperanto, and am gradually becoming conversational in Spanish (still struggle with verb forms, but I can usually get my point across).
In the "do I really 'speak' it?" territory are American Sign Language (I took classes for five months, but then we moved and I didn't have anyone to practice with so I didn't practice) and Russian (I learned the alphabet and some words and sentences, but can't really have a conversation beyond greetings and introductions).
In the "is it really a 'language'?" category is Toki Pona, a minimalist language with about 120 words (the assorted obsolete and unofficial words make counting them a bit less straightforward). I speak it quite well, and can express and understand more than I thought would be possible (I even wrote a singable translation of "O Holy Night"), but the vocabulary makes it hard to say things like "hope" and "sit"! These limitations make me hesitate to consider it a full language.
I also know most of the grammar, and some vocabulary, of Lojban (a constructed language based on predicate logic) and Klingon, but remain an eternal beginner, so I don't count them as languages I speak.
I have a long list of languages I want to learn; if I achieve conversational fluency in Spanish by the end of the year, I plan to focus on Russian next year. I also still want to master ASL. Also fairly high on the list are Italian and Korean, and I'd like to learn German and Japanese sometime! If only I really could become "Fluent in 3 Months", but that hasn't panned out for me so far! :-P
