Oh, dude, the collective noun for pistols is a "brace." It's like when a bunch of pistols get together and decide to hang out, they're like, "Let's form a brace, bro." So yeah, if you ever see a group of pistols chilling together, you can call them a brace and sound all fancy and stuff.
It usually says right on the barrel. Single shot / single load pistols are pellet pistols. Most BB guns have a reservoir for the BB's. There are a few that shoot either a BB or a pellet. You will have to look at the instructions or the display box to see what it says. Pellet pistols are more accurate than BB pistols. Most BB pistols will say .177 BB. Pellet pistols will say .177 Cal and not say BB.
It depends on the brand. You can find really cheap pistols in some pawn shops and some gun shops for under $100...then from there, you can spend as much as you want basically. Nighthawk pistols are close to $3000, some pistols are more expensive. And there is something available at every price point in between.
