generally the deadlift is the last or second to last of those lifts to stall. overhead press is where most people find slower progress.
there could be a few reasons why your deadlift isn't getting better, from your back strength, your form, your grip, etc. it might be helpful to get an experienced lifter to watch you while you deadlift, or try to get a video of yourself and post it here or a lifting site for some critique.
are you following a specific program? your numbers seem a little skewed...can you really bench press more than you can squat? that seems backwards.
