Your first one is Spanish colonial, I
think it's a 1 real, Mexico City mint. Charles IV of Spain ruled 1789-1808, so I'd guess the date is more like 1797. 1797 Mexico City 1 real coins catalogue at $5 in low grades.
Coin number 2 is Swiss; "Helvetia" is the Latin name for Switzerland. Swiss coins basically haven't changed design since your coin was issued;
Here's a forum thread with a modern half-franc of the same design. Your one is pretty worn; catalogue says $4 or so.
Coin number 3 is from the Nazi puppet state of Vichy France. It's made of aluminium (you can spell it "aluminum" if you like). Common enough; catalogues at 50¢ to $1 in that condition.
Coins number 4 and 5 are from pre-war France. Coins from some countries are "holed" because the locals don't have pockets; I don't think that's the reason for these French coins, though. It's probably more to do with making sure no-one confuses them with the silver coins which were about the same size. Worth about 50¢ each.
