It would be better if you had some concept of how big the room is compared to what you'd like to do as displayed in your sketches.

Here is your floor plan with a grid that indicates 1 square equals 1 ft. The red dotted lines are the openings to the dining room and foyer. You cannot place anything across those openings.

Here are two possible layouts for your room so far. This first layout has a 9ft. sectional, modest in size and that corner is the ONLY corner where a sectional can fit. The lounge chair is 3 ft. square, a standard size for most lounge chairs.

Here's another layout for the room with an 8 ft. sofa and two lounge chairs

You could place a small sectional (if it only has a chaise) in the center of the room and have 3' to walk behind the sectional but it's tight.

Thank you for the detailed explanation! This really helps , yes sorry my drawing of the couch wasn’t that great .
