Let's go through a condensed history of Palestine since the Romans so you can quit making a fool of yourself.
Palestine was conquered by the Romans, but they did not settle their people there. They ruled the native people and imposed a law that required the native people to convert to Christianity from the various religions they had been following when Christianity became the state-religion.
It was conquered by the Persians in 614 and the Persians ruled the native population, they did not settle their people there.
In 628 it was reconquered by the Romans (Byzantines), and again the Romans ruled the native people and did not settle their people there.
In 637 it was conquered by the Arabians/Saracens. They also ruled the native people, but did not settle their people there. Many of the native Christians converted to Islam.
In 1099 Palestine was conquered by the Christian Crusaders who ruled for a little over 100 years. Many of the Muslims re-converted to Christianity.
In 1187 Saladin, the Kurdish ruler of Egypt, conquered most of Palestine, including Jerusalem, the Egyptians also ruled the native people and did not settle their people in Palestine.
In 1250 Saladin's Ayubid in Egypt fell and was replaced by the Mameluks who continued to rule over Palestine's native people but did not settle Mameluks in Palestine. Mameluks being a warrior class made up of Christian converts to Islam from Georgia, the Balkans, Coptic Christians, etc.
In 1515 the Ottomans defeated the Mameluks and Palestine reverted to Ottoman rule. The Ottoman's did not settle their people there, they ruled the native people as previous rulers had.
In 1918 the Ottomans were defeated by the Allied Powers and Palestine reverted to the administration of a Mandatory, Great Britain. Great Britain did not settle its people there but did settle European Jews in the territory.
As you see, your assertion that somehow Syrians, Lebanese or Egyptians (unless you mean Mameluks or Saladin's Kurds) invaded or colonized Palestine, is an historical impossibility. As far as the Turks, there was no evidence of a Turkish presence except for the military garrison and administrators when the British conquered Palestine in 1917 as the 1921 Report of the Mandatory to the League of Nations indicates.
