#1 is a token with what looks like Arabic text, but it may not be actual Arabic.
#2 is Egypt, 1/20 qirsh, 1327/2 (second year of Muhammad V's reign which began in 1327). In our calendar this is 1910.

Your bottom coin is actually from Algeria, 1 centime 1964. The bottom picture is upside-down.

Your cupronickel Egyptian coin is dated accession 1327 regnal year 2, which converts to AD 1910.

Your first coin is, as Nalaberong said, not actually a coin. It roughly imitates the old silver coinage from what is now Algeria; here's what a genuine coin looks like. They were made as costume-jewellery pieces. In many Middle Eastern cultures, wearing coins on festive occasions (weddings, etc) is traditional. For folks that can't afford real gold and silver coins, they wear things like this. Do a forum search for "imitation Ottoman Algeria" and you'll find numerous similar examples posted on the forum before, like this one.

Taiwan, 1 jiao, 1955.

I am told this coin is from Thailand.

Your Thai coin is indeed from Thailand, a 1 baht dated Year 2549 in the Buddhist calendar, which converts to AD 2006.

Your Canada piece used to be a coin, but it's had one side ground flat and had someone's initials engraved onto it. It's now a "love token". The dark grey streak across the face is probably where a pin or lug was attached, for turning it into a brooch or button.

This looks like a British coin but I can not find it in a book.

There appears to be an 80 under the queen.
The reverse is upside down to the obverse side.
the figure on the reverse is sitting the opposite direction to a British large one cent.

The portrait is very distinctively the one used on British coppers in the 1806-1807 series (farthings, halfpennies and pennies). Which one you've got depends on how big it is.
