please help me indentify these trees and plants

ive recently brought a allotment plot and there is a small orchard and need help identifying these fruit

is this brown rot on this plum tree?

 

I see what looks like a pear an apple and raspberry. It might make it easier to give identity guesses if you numbered the photos depending on what you are showing in them. Not seen anything like the last photo.

 

That could be brown rot, it looks like there are stems holding what were the plums which have rotted.

 

Yes it looks like brown rot on the plum tree remove the dried fruit and burn ASAP. The two pictures above show raspberry canes. The one above those looks like an apple.

 

so the plum tree is ok, i just need to remove old fruit? it has new blossom coming on at the moment

 

Are 3 and 4 shrubs? If so could be Blackcurrants, but may have Blackcurrant big bud mite / RHS Gardening

I'd guess the first one is a Pear as it's in blossom early.

 

OK, 2nd guess is Quince (not Japonica). I've got one at my plot and will have a look tommorow.
