It all sounds pretty normal but I know it's very tiring.
There are a few things you can try though.
Try feeding every 2 hours in the day and use breast compressions, this should encourage him to get as many calories and cuddles as possible in the daytime.
Get him outside in day at least twice. They don't yet know the difference between day and night but getting them outside can help them to learn the difference, sunlight also aids sleep. If DH is still on PL, do the first feed then hand him over to DH to change and go out for a walk, even if it's just around the garden.
If the cluster feeding is getting to you in the evening, do some breast compressions, then hand him over to DH and get him to take LO out either in the pram, car or in a sling. My DD was always fast asleep before they got out of our street.
Use a T-shirt that DH has worn as the sheet in his Moses Basket. The smell of DH should be reassuring and help him to settle.
Don't be afraid to spend a couple of days in bed with LO either, just feeding and sleeping
