@GoodEgg all the information you want is below. Enjoy.
World War 2
The Star is the 1939-1945 Star issued a to all British and Commonwealth Service personnel.
The Blue and Red Ribboned Medal is the War Medal issued to all Service men and Merchant Navy for 28 days or more of continued service between 1939-1945.
The Green and Orange medal is the Defence Medal usually issued to non-military personal between 1939-1945, however military personnel could be awarded if they attained one or more campaign stars like your Star.
World War 1
The red, white and blue ribbon on its own is the WW1 Service Medal ribbon which should be attached to a star with large crossed swords through it.
The medal with the Horse is the British War Medal.
The Gold coloured medal is the Victory Medal.
All these medals can easily have there ribbons replaced via medal outlets or ebay very cheaply but will add to their provenance and beauty.
The last one threw me a bit as it isnt actually a medal of any kind let alone a campaign medal. It is a Thaler, to be precise it is the Maria Theresa thaler
Which is a Austrian silver bullion coin dated 1780.
If its an original and in very good condition its worth in excess of £2000, however they have so many variants and conditions. Yours has an edge loop but this is not for a ribbon its for a necklace as over the years as the value diminished as a currency in trade they were used for other forms such as jewellery.
Ethiopians commonly turned them from coins to medallions for some reason, and you can visibly see the edge burns where the loop has been fused to the medallion.

I would encourage you to speak to a coin and token specialist to establish this coins value and history.
