Can the string be attached from the side? What if the tzuras hapesach cannot withstand a normal wind? What is the din of a rooftop that has no walls and extends beyond the walls of the house (an overhang)

It is disqualified if there is more gap then fence , or if there is a gap bigger then 10 amos. If it is an alleyway that many people pass through then you need a tzuras hapesach if it it is 4 tefachim wide. When it comes to corners any 4 tefachim gap disqualifies it.
The famous dispute between Rashi and the Rambam how many mechitzos are needed to categorize an area as a Reshus HaYachid.
What is the din if there is a space between the ground the start of the wall? What if the mechitza cannot withstand a normal wind?
A Tel HaMislaket is a hillside which has a steep slope and can be used as a wall. This particular slope is based on the Talmudic definition for a Tel HaMislaket of “within a distance of four Amos [cubits] the rise of the hill should be 10 Tefachim (hand breaths).
What is the din in the following cases? If one placed an item on high column that is found in a Reshus HaYachid, on the walls of a Reshus HaYachid, in holes of the wall of a Reshus HaYachid.
“Reshus Hayachid” is a private domain which contains an area of at least four tefachim by four tefachim and is generally surrounded by enclosures at least 10 tefachim high. The enclosures can take a variety of different forms. It can include a post office box, large dumpsters and pits.
The term eruv is a shortening of eruv chatzeros (עירוב חצרות), literally a "merger of [different] domains" (into a single domain). This makes carrying within the area enclosed by the eruv no different from carrying within a single private domain (such as a house owned by a single person), which is permitted.
The eruv typically includes numerous private homes, as well as a semi-public courtyard whose ownership is shared by them. To enact the merger of the homes and courtyard into a single domain, all home owners as well as owners of the courtyard must pool together certain foodstuffs, which grants the area of the eruv the status of a single private domain. As a precondition for this merger, the area must be surrounded by a wall or fence.
