Nice varied collection there. Sadly your two most valuable UK coins are the half sovereign and the sovereign from your earlier posts!
Row A number 6 is as 1995 GB £2 coin celebrating the 50th anniversary of the end of World War 2. Details here, also for your 1989 Bill of Rights coins:

Of the rest, the 1910 Farthing is probably the scarcest/most collectable. The silver probably isn't worth anything more than scrap value, but your threepence C7 is nice and pretty.
If you didn't already know, anything before 1920 is 92.5% silver and anything from 1920 to 1946 is 50% silver. After that, there is no silver in the coins.
A2-A5 are crowns, face value 25p rather than £5 sadly and aren't worth much/any more than face value (£1 each absolute tops).
The 1912 H penny is interesting but pretty common in that condition and perhaps worth £1 on eBay?
Can't help you with A1 or B3 but I'm sure someone else might.
Thanks for sharing, I like them anyway!
Edit: 1892 Farthings are also quite scarce, so that one might be worth about a fiver. Your 1900 Crown is perhaps worth £25 and the 1887 perhaps £50-£75?
To give you some idea of values, this is quite a good resource and quite easy to navigate. Prices are what you might expect to pay from a dealer rather than what you might be able to sell it for, but it's a useful guide:
