Drive shaft bolts - If your after the torx head ones, they are NLA from Ford.

If it's 2wd they are fine pitch thread about a £1 a bolt and you need to get them zinc'd as they come self colour.

If it's 4wd your in luck as I bought a set of 25 for £4.

Diff cover bolts you can buy from Ford, they come in a dull black anodised finish. Or you can get a socket button stainless bolts for peanuts.

Rear beam bolts are std M10 and M12 for the longer ones and the 2 that go through the steadying plate

The flanged M10 trailing arm's are NLA from ford however you can buy the Puma bottom arm bolts and they are identical but 5mm longer

Diff mount bolts are high tensile 10.9, you can get these in 12.9 zinc cheaply as well

Your Blue prop bolts are a ford only item as they are fine pitch and the blue is the lock thread.

I would go to a local fastener place with the ones you need or measure them up before hand.

I know the longest bolt that goes through the diff to rear beam is the hardest one to get as it's an odd length (210mm from memory)
