There isn't really a difference. The first one if probably better, as the punishment has been completed, so you should use 'have been'. But both make sense

They both mean the same thing, and you can use either. I think it's just personal preference. I would normally use the second

What's the context? It could mean a lot of things, especially if it is regional slang

Change develops to developing. The rest is fine and sounds pretty natural

Don't be cheesy. Don't be lame.

It means to understand something properly. "I just can't get my head around these instructions" "I just can't understand these instructions"

1) yes that's fine. You can also say "I'm on the road with a Walmart", or "I'm on the road next to Walmart". They all work in English. 2) That sentence makes perfect sense. 3) You would say "I bought a Ralph Lauren shirt". Although Ralph Lauren is technically a person, you are referring to the company, not the man himself, so you don't need the -'s. I would say "That shirt is Ralph Lauren" or possibly "That shirt is from Ralph Lauren" Again, if I was referring to Ivanka Trump's brand, rather than her personal dress, I would say "I bought an Ivanka Trump dress". I don't think you need the word 'brand' in this context, as it seems obvious this is what you mean, but you could say "I bought an Ivanka Trump brand dress". Either way, I wouldn't use the -'s at all.
