Can this garden be levelled out or would it interfere with DPC?

I'd be most worried about the damp proofing detail where that funny little wall touches your house. If that corner of next doors gets water logged it's only got one place to go. It should have been built on their side and then would be below their DPC but instead it's on your side above it. Tell them to dog leg it over a bit or cut a gap between it and your house.

Would some weep holes in the wall help?

Guys, just been to the house and had a closer look... so it actually looks like this! I thought the grass was all the way up to the wall but no. Also the air brick isn't directly on the ground. There is one brick below it. Is this acceptable?

Pretty much every house in the development is like this but just need to be careful because ours is the only one with the garden sloped towards it, so if the space fills with water it could still get in.

I would suggest yes, that should be fine - subject to checking the DPC level is clear.
