Yes, you can StreetPass with the same person multiple times in one day. Each time you pass by someone with a compatible device, a new StreetPass interaction can occur, allowing you to exchange data, such as game information or Miis. However, the frequency of StreetPass interactions may depend on the specific game and the data being exchanged.
In order to increase the level of Miis for Streetpass Find Mii, you need to streetpass the same Mii more than once. The number of times streetpassed is directly proportional to the level of the Mii up to Level 7.
Deleting your Streetpass notifications deletes all your Miis and cannot be recovered.

If you click on Mario Kart Channel, you'll see a screen with all your friends on StreetPass. If you click on the right section next to StreetPass list (where your Mii face is), you will see how many games you have won on local an online multiplayer, how many coins you have collected, and how many StreetPass hits you have had. The best thing about the Mario Kart Channel is that you can create your own Grand Prix and send it to your friends via StreetPass.
