Orders for new manufactured goods rose 1.5 percent in May while shipments for the month advanced 2.6 percent, the largest one-month gain since October 1980, the Commerce Department reported today. At the same time, the department reported that the value of inventories of unsold goods fell 1 percent in May, to $271.5 billion, marking the fifth decline in the last six months. Such declines are considered a sign of future economic strength on the ground that inventories will have to be rebuilt eventually through new orders.

International The President discussed the crisis in Lebanon in greater depth than previously in a televised news conference. Mr. Reagan said his Administration had given ''no green light whatsoever'' to Israel to attack west Beirut, but he endorsed Israel's demand that all Palestinian guerrillas in Lebanon be withdrawn. (Page A1, Column 6.) Talks in Beirut made some progress as negotiators for the Lebanese Government and the Palestine Liberation Organization sought an agreement on how and when the Palestinians should leave Lebanon. (A1:4-5.)

The Supreme Court today struck down a New York State law that required landlords to permit the installation of cable television equipment for a $1 fee. In a 6-to-3 ruling, the Court said the law effected a ''taking'' of private property by the state without the ''just compensation'' required by the Constitution. Writing for the majority, Associate Justice Thurgood Marshall said that the law required landlords to sustain a ''permanent physical occupation'' of their property. ''Such an appropriation,'' he said, ''is perhaps the most serious form of invasion of an owner's property interests.''

The board of the Metropolitan Transportation Authority decided yesterday to postpone at least until December proposed increases in subway, bus and commuter fares. As a result of the decision, the State Financial Control Board voted unanimously last night to grant a six-month - rather than a one-year - approval of the authority's financial plan for fiscal 1983, which begins today. The M.T.A. board had been considering a 20-cent increase in the 75-cent subway and bus fares, as well as rises of 33 percent in commuter fares on the Long Island Rail Road and in the metropolitan region of Conrail. These facilities are used by nearly six million passengers each working day.

The Boeing Company pleaded guilty in a Federal court here today to failing to disclose payments of at least $7 million in commissions to overseas agents to help win orders for 35 aircraft valued at $344 million. Boeing, the world's largest manufacturer of commercial jetliners, pleaded guilty to 40 counts of filing false statements with the Export-Import Bank in connection with its financing of aircraft sales to airlines in Spain, Lebanon, Honduras and the Dominican Republic in the early 1970's. Under the plea entered in the United States District Court, Boeing agreed to pay $400,000 in criminal fines and $50,000 in court costs to end a five-year-long Justice Department investigation. The Government agreed not to bring any charges relating to foreign payments that might be disclosed in later company filings with the Securities and Exchange Commission.
