#1: not ancient, and not a coin. I think it's an Indian "temple token", Islamic type. There are some with this design
on zeno.ru, described as coming from Arabia.
#2: Kushan Empire (100-300 AD, situated in northern India/Pakistan and southern Afghanistan). Check the examples on
this page for coins of similar style.
#3: Not ancient, but it is a coin: Indian state of Gwalior, 1/4 anna, AD 1901 (1958 in the local calendar). Listed in the Krause world coin catalogue as KM# 169, valued at a dollar or two in that condition. Trivia: the swirly thing is the prince's badge, a cobra snake with crossed sword and trident.
#4: a coin from mediaeval Sri Lanka (formerly known as Ceylon), circa 1000 to 1400 AD. The pics are a bit fuzzy to say any more than that.
This old thread discusses some coins like this;
this even older thread has someone else asking about one of these coins.
#5: Roman, circa 100-150 AD judging by the portrait. Reverse, somebody marching left. We'll definitely need better pics to attribute this one properly.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
