President Ferdinand E. Marcos of the Philippines has rejected a plea by the Reagan Administration for major political, economic and military changes to avert further turmoil there, Administration officials said today. President Reagan's personal envoy, Senator Paul Laxalt, Republican of Nevada, returned late Thursday night from Manila aboard a United States military plane after a series of meetings with Mr. Marcos. Mr. Laxalt requested a White House meeting with Mr. Reagan ''as soon as possible,'' an aide to the Senator said. A White House official said President Reagan would probably meet Mr. Laxalt on Monday or Tuesday.

Sitting on the dais, Eugene Lang, multimillionaire industrialist, suddenly realized the commencement address he was about to deliver was complete balderdash, to put it nicely. He was about to tell 61 sixth-graders in a warm Harlem auditorium that he had also attended P.S. 121, a half-century ago, that he had worked hard and made a lot of money, and that - quick, the No-Doz! - if they worked hard maybe they could be successful too. Instead, Mr. Lang, a magnate with a no-nonsense style, stepped to the podium and told the graduates that if they stayed in school he would pay the college tuitions for each and every one of them: college educations on the house! There was stunned silence, peppered with a few audible gasps. Then students, parents and teachers cheered and mobbed him. ''I have never kissed so many strangers,'' Mr. Lang recalled. He told them that he was thereby earmarking $2,000 for each of them toward college tuitions, that he would add more money each year that they stayed in school and that their college tuition was assured.

Despite international appeals for clemency, a black supporter of the outlawed African National Congress was hanged today in Pretoria for his role in the 1982 murder of a security policeman. The execution of the black activist, Benjamin Moloise, 30 years old, set off rioting by hundreds of blacks in downtown Johannesburg. Two white policemen were stabbed, a black man was shot by security forces and at least eight white pedestrians were beaten on the city streets. President P. W. Botha had received appeals from around the world to commute the execution, including appeals from the United States, the Commonwealth, the European Economic Community and the United Nations. The United Nations Security Council passed a resolution last year calling on the South African authorities not to execute Mr. Moloise. [In Washington, a State Department spokesman said, ''We have made plain our opinion that clemency in this case was justified.'' At the United Nations, Secretary General Javier Perez de Cuellar deplored the hanging, and the Organization of African Unity denounced what it called the South African Government's ''act of barbarism.''] Mr. Moloise's lawyers had asked that the case be reopened because of new evidence that they said would have led to commutation of the sentence. Mr. Moloise was sentenced to death in September 1983 for the murder of the security policeman 10 months earlier.

The first evidence that an Air-India jumbo jet may have been destroyed by a bomb has been detected on a fragment of the fuselage brought up by a salvage ship, an American official said yesterday. The Boeing 747 crashed into the sea off Ireland last June 23, killing all 329 people aboard. Holes apparently caused by objects that pierced the skin of the plane from the inside have been found in a piece of belly skin from the forward cargo area, according to an official from the National Transportation Safety Board. Asked if this was proof that the plane had been blown up, the safety board official said the evidence was preliminary, but acknowledged that it pointed in the direction of a bomb.

President Reagan tonight sent a special representative to Italy, Tunisia and Egypt in an effort to ease tensions with those countries, Administration officials said. The envoy, John C. Whitehead, Deputy Secretary of State, was carrying messages from Mr. Reagan to the leaders of each country in an effort to rebuild confidence, the officials said. The disputes with Egypt and Italy arose after the hijacking of the Italian cruise ship Achille Lauro, in which a 69-year-old passenger, Leon Klinghoffer of New York, was slain. #2 Destinations Confirmed The State Department tonight confirmed Mr. Whitehead's visit to Italy and Egypt. Because of the sensitive nature of relations with Tunisia, there was no announcement of the stop in Tunis.
