You can filter all columns with Area in columns names by DataFrame.filter, compare by DataFrame.eq for == and test if all Trues per rows by DataFrame.all:
df['Status'] = df.filter(like='Area').eq('Completed').all(axis=1)
Or you can seelct all columns without first 2 by DataFrame.iloc:
df['Status'] = df.iloc[:, 2:].eq('Completed').all(axis=1)
Or last 3 columns:
df['Status'] = df.iloc[:, -3:].eq('Completed').all(axis=1)
