President Reagan yesterday filled three sub-Cabinet spots in the Labor Department, two in Agriculture, and one each in State, Justice and Housing and Urbine Development -- and even named a woman to one of them.

Reagan nominated Carol E. Dinkins, a lawyer from the Houston firm of Vinson & Elkins (the firm of former Texas governor John B. Connally) to be assistant attorney general for land and resources.

The three Labor Department slots went to Washington labor lawyer T. Timothy Ryan Jr., nominated as the department's solicitor; Florida construction contractor Thorne G. Auchter, named assistant secretary for occupational safety and health, and Albert Angrisani of Chase-Manhattan Bank, nominated as assistant secretary for employment and training.

At the Agriculture Department, William Gene Lesher, a former economist for the Senate Agriculture Committee and former legislative assistant to Sen. Richard G. Lugar (R-Ind.), is the choice as assistant secretary for economics, and John B. Crowell Jr., general counsel for Louisiana-Pacific Corp., will be assistant secretary for natural resources and environment.

Over at the State Department, it will be James L. Malone, a Washington lawyer who headed up the transition team at the Arms Control and Disarmament Agency, as assistant secretary for oceans and international environmental and scientific affairs.

At HUD, Philip D. Winn, a Colorado real esate developer, was nominated to be an assistant secretary and a federal housing commissioner.

Reagan also ignored appeals from church-state separationists to leave the position vacant and named William A. Wilson, a longtime friend and "kitchen cabinet" member, as his personal representative to the Vatican. The United States has no formal diplomatic relations with the Vatican, but former presidents Franklin D. Roosevelt, Nixon and Carter named personal envoys.
