Seven? Luxury. I still only have five.
Use a small electrical screwdriver and check the face of the teeth, if you can feel a small lip at the edge that would suggest that it is worn.

If your motor isn't on the back wheel (and it doesn't look like it is) then just get a new cassette and fit. If you're sure the chain measures up ok then it should cure the jumping. There can be other reasons but the obvious one is a worn chain/cassette. It does look a bit worn in the photos.
Thank you. I have replaced the cassette and I can see the improvement however some gears still like to slip so I reckon it developed some misalignment or derailleur got bent and I think these adds to the wear of the cassette.

Then replace the chain as well. Always new cassette = new chain. Save the old one (if it's still <0.5% elongated): it can be fitted after 1000 miles and you can swap 'em round every 500.
