Chaenomeles and Kalanchoe?

Yes, Chaenomeles and Hylotelephium.

Or in laymen's terms, flowering quince and an upright sedum :-))

Thanks! I think my grandmother must have planted them long ago. Maybe I can find some more to buy in a nursery. Do you think the bushes would grow from cuttings?

Yes, you should be able to root the quince - if you know a suitable method first. When using a web search try a phrase like "chaenomeles cuttings".

It is very likely the quince is producing suckers......in which case you can quite easily remove one or more of the perimeter ones with roots intact = instant new plant!!

You can divide the sedum, just carefully lift out the plant with as much root area as possible then cut the root mass in half then replant. For the quince you can simply bend a few branch,s down to the bare earth and place a small softball size stones on the branch holding in contact with the earth, roots will form in a few months. Then cut the branch free above the newly formed roots. You will have a nice rooted cutting ready to plant!!

You could also grow new Sedum plants from the leaf cuttings: https://www.google.ca/search?q=sedum+leaf+cuttings&client=firefox-b-ab&dcr=0&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj9-NHG1OfZAhVZVWMKHUhNCEsQ_AUICigB&biw=1006&bih=607

And one can cut stems of Sedum & stick them in the ground.

I usually have good success rooting quinces by sticking cuttings in the ground where I want them grow. In the winter when the ground gets moist and will stay moist until spring/summer.

The Hylotelephium is struggling rather amongst the Euonymus and grass. It would do better in a sunny cultivated bed and at present looks a bit too weak to divide yet. Your Chaenomeles has a branch of Eleagnus growing up through it. Looks as if you have your work cut out, it appears to be a bit of a jungle there ;-)
