Conclusion of Sugya: Amount of walls needed to create a Reshus Hayachid

Major Question on ר”ח and Rambam:

In the answer of the Gemara having three walls and a lechi is considered a Reshus Hayachid.  But according to Rava לחי is a היכר why is this Mavui considered a Reshus Hayachid?

Why does ר”ח say the tikun on the third side is a door? Why not a Tzuras hapesach?

Questions on Rashi:

How could Rashi say the Rabanan agree to Rebbe Yehuda that only need a lechi or korah on each side? The Gemara on Daf 6a said the rabanan require a tzuras hapesach on one side and a lechi or korah on the other?

If Rebbe Yehuda holds two mechitzos create a Reshus Hayachid where is there a case of a סרטיא or פלטיא that is considered a Reshus Harabim (listed in גמרא שבת דף ו) as their roads had walls on the side of them?

Question on halacha אין צריכין ליגע – side posts do not need to extend until the top crossbeam. 

Why not?

See משנה ברורה שס”ב ס”ק סב which says the reason is because of גוד אסיק

Major Question:

In the Sugya of כיפה  in the case of a doorframe which is an arched on top. The gemara says if the side posts are ten tefachim tall everyone agrees it’s considered a צורת הפתח.  Rashi says this is a proof that the side posts do not need to extend to touch the top cross beam. 

How could this be considered a צורת הפתח  through גוד אסיק , there is solid material separating the top of the side posts and the cross beam?
