1 cotoneaster, couldn't say which one
the little red/orange one is Scarlet Pimpernel, a rather lovely native annual
the next is some sort of potentilla, does the pink flower belong to it? if it does it's not the weedy Potentilla reptans which the leaves resemble.
The last is not oak, a better look would help. might be some kind of sorbus, doesn't look quite right for hawthorn
