The 2 on the left are Canadian 1951 pattern Browning Hi Power holsters. The white one is a military police example. Prices? I have seen them for sale as little as $5.00 to $50.00. The white one probably worth less than the original green one, unless you are a military police militaria collector perhaps? The middle holster stamped US is a Vietnam war era 1911 service holster. A brand new example can be had for around $65.00 USD these days (Moore Militaria). Yours looks like used condition so probably worth less to collectors. The 2 on the right? No idea? Some kind of commercial holsters. You would probably do good if someone gave you $20 or so for them.
