English, Arabic, Japanese, a little French, & I could somewhat understand bits of other latin languages.
To follow Danzaivar's example: Pascal, C, VB, C++, HTML, JAVA, & soon PHP, ASP.Net, C#.
EDIT: Just realized what a weird combo I have. English I learned fluently because I spent my school life in International schools (watching movies helped too).
Japanese I learned before Arabic, since I spent 1st & 2nd grades in Japan International School. I didn't become great at it 'til (ironically) I returned to Iraq, where my siblings' stashes of manga, anime, & magazines helped me advance tons.
Arabic I learned in Baghdad International School (now reduced to a pile of ashes
http://members.lycos.co.uk/isbaghdad/) & 'til now am pretty messy at it, mostly due to lack of mixing with people that speak Arabic.
3 completely different alphabets (4-&-beyond if you consider Japanese). 3 different grammar systems. I'm impressed with myself ^^
