Chalkland flowers for ID please

[Jonners]

I took a brief walk along the Devil's Dyke near Newmarket today and saw the following flowers for which I would appreciate positive ID. I've had a stab at some of them, but I'm no flower buff:
1.

and the leaves at the base of the flower stems:

Query Dropwort, filipendula vulgaris?

2.


I think this is the same:


3.

Query Pyramidal Orchid, but note also the tiny caterpillar!


I'm pretty sure this one is a Pyramidal Orchid

4.

Query Yellow Meadow Vetchling, lathyrus pratensis

5.

Query Sainfoin, onobrychis viciifolia

Sorry if the photos aren't up to scratch

I hadn't thought of that. I could have given it a rub to see (smell).

The yellow one is common birdsfoot trefoil Lotus corniculatus

I think your two Pyramidal Orchids and the Sainfoin are correct (someone on another thread mentioned there were many Pyramidal Orchids on the Devil's Dyke at Newmarket).

I see a lot of Sainfoin on the chalk downland in my area. Apparently it was once grown as a fodder crop.
