You can have up to 100 friends in your Friend List. And no, if you're playing a non-3DS game (that is, a Nintendo DS game or DSiWare), it won't show what you're playing because you can't go online while playing DS software.
Okay thanks, lastly I met someone using streetpass and now hes in my plaza I can view his recent game, his info.... but thats it I thought he was suppose to give me a puzzle piece.
You have to go to "Play" (to the right of your Mii) and click "Puzzle Swap". There's also Find Mii, a little RPG game that uses the Miis you meet through StreetPass, too.
It says I haven't met anyone but he's right there in my lobby left of settings. :/
Did you update your system? Before the latest update, if you don't play Puzzle Swap and/or Find Mii with the Miis you collect before you close StreetPass Mii Plaza, you can't use them to play the games next time you go back. In the newest update it saves the Miis you've collected if you haven't used them yet, though.
OH! Okay that must be it thanks.
Added and updated!

I'm not doing it to get Bells, I don't even use the stupid shop. >_> I do it so people still see the list if they go to the last page instead of the first. Spoilering it would make it easily missed.
