Can i put 468×60 along with 2 leaderboards and 1 Square Ad unite?

As my title says, i wanted to if it is possible to put one 468 x 60 banner along with the flowing Ad codes running already on a page:
Leaderboard 728 x 90 = 2
Square 300 x 250 = 1
Link Unite 468 x 15 = 1
Can we still put 468 x 60 banner on that pages? Thanks.
