Please Help Identify Some Old Coins (Gold & Silver?)

Taking the first question mark on the left :
The crudely-made hexagram piece is Moroccan. The same goes for the others with the same design, including the one which apparently is dated 1786.
The one with the center hole is Japanese, cupronickel 10 sen, dated Taisho 12 = 1923. The one immediately below it in the photo appears to be a small-denomination European silver coin of the 19th century.
At the second question mark :
The yellowish piece with the hole may possibly be an Ottoman/Turkish or Persian gold coin, or more likely a jeweler's imitation, which for a long time were sold in the bazaars as a convenient form of bullion.
The other piece looks as though it might be a British small-change token of the time of George I.
At the third question mark :
The one with the woman's head (Arethusa) & four dolphins would be an ancient Greek silver tetradrachm if genuine, but is probably a replica.
The copper piece may be a Dutch provincial coin from before the Napoleonic wars.

If you want any better information, you will have to supply better pictures.

Great guys thanks for now, I will supply better pics later on :)
