With your second question, to stand RIGHT AT THE FRONT emphasizes the location. For example, the first person in a line of people waiting to get into a movie is RIGHT AT THE FRONT. The second or third person in the line could be described as at the front, but the first person is RIGHT AT THE FRONT. Hope this helps

1. He gets dressed. 2. Right = directly. It emphasizes the "front" part of his location. Not only is he at the front but he's first (if you're talking about a line) or in the first row (if you're talking about a crowd). And yes that's fine to stay but slightly different. 3. marry well = marry someone with money and status

Thank you very much.

1- He puts on his clothes. To have an article of clothing on means to be wearing it. 2-The usual way that sentence goes is 'He is standing right in front' or 'He is standing in front'. Nonetheless, they are both the same. 3-'to begin with, I expect to marry well' where 'to begin with' can be interchanged with 'in the first place' which are usually used when talking about the first stage of a situation.
