It doesn't matters which address you check, all will show same balance and same transaction id's.
The first character of an address is roughly the "type" of the address. Technically, if you unpack an address from its base58 form, the first byte will be the "version byte".

A Bitcoin address, or simply address, is an identifier of 27-34 alphanumeric characters, beginning with the number 1 or 3, that represents a possible destination for a Bitcoin payment. Addresses can be generated at no cost by any user of Bitcoin. For example, using Bitcoin-Qt, one can click "New Address" and be assigned an address. It is also possible to get a Bitcoin address using an account at an exchange or online wallet service.
An example of a Bitcoin address is 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy.
