I don't know the below codes can satify your requiremnt or not.
Also you can deal with  the return cursors in your purpose.

CREATE OR REPLACE PROCEDURE SP_PROC_TEST_MULCUR(IN_ID NUMBER) IS
    V_CUR1 SYS_REFCURSOR;
    V_CUR2 SYS_REFCURSOR;
    TAB_T1 TEMP_TEST%ROWTYPE;
    TAB_T2 TEMP_TEST%ROWTYPE;
BEGIN
    SP_PROC_TEST(IN_ID, V_CUR1, V_CUR2);
    LOOP
        FETCH V_CUR1
            INTO TAB_T1;
        EXIT WHEN V_CUR1%NOTFOUND;
        LOOP
            FETCH V_CUR2
                INTO TAB_T2;
            EXIT WHEN V_CUR2%NOTFOUND;
            IF TAB_T1.ID = TAB_T2.ID THEN
                DBMS_OUTPUT.PUT_LINE('TAB1-ID:' || TAB_T1.ID || 'NAME:' ||
                                     TAB_T1.NAME || 'STATUS:' ||
                                     TAB_T1.STATUS || '||TAB2-ID:' ||
                                     TAB_T2.ID || 'NAME:' || TAB_T2.NAME ||
                                     'STATUS:' || TAB_T2.STATUS);
            END IF;
        END LOOP;
    END LOOP;
END;

hope this works....

CREATE OR REPLACE PACKAGE Client AS
	TYPE cursor_type IS REF CURSOR;
PROCEDURE spGetClient(cur_Client OUT cursor_type,cur_Client1 OUT cursor_type );
END Client;
 
CREATE OR REPLACE PACKAGE BODY Client AS
 
PROCEDURE spGetClient (cur_Client OUT cursor_type,cur_Client1 OUT cursor_type )as
	BEGIN
	open cur_Client for
			SELECT     clientid,clientname			
   FROM     TBLCLIENTMASTER 
			WHERE ISACTIVE=1;
			
	open cur_Client1 for
			SELECT     clientid,clientname			
   FROM     TBLCLIENTMASTER

	END;
	
END Client;

and in the code behind write this....

And in place of OracleHelper.ExecuteDataset write you own function.

public DataSet fnGetClientList()
		{
			DataSet dsData = new DataSet();
			try
			{
				OracleParameter[] storedParams = new OracleParameter[9];
				
				storedParams[0] = new OracleParameter("cur_Client", OracleType.Cursor);
				storedParams[0].Direction = ParameterDirection.Output;
				storedParams[1] = new OracleParameter("cur_Client", OracleType.Cursor);
				storedParams[1].Direction = ParameterDirection.Output;
				dsData = OracleHelper.ExecuteDataset(strCnn, CommandType.StoredProcedure, "Client.spGetClient", storedParams);
				return dsData;
			}
			catch (OracleException excSQL)
			{
				throw excSQL;
			}
			catch (Exception excError)
			{
				throw excError;
			}
			finally
			{
				dsData = null;
			}
 
		}
