No would be a general answer. More info on your goals and experience would help in figuring out what's best for you though.
That said, 5x5 volume is great for most people, epsecially newer lifters if that is what you are. And as long as you are progressing in weight on the lifts, you are adding muscle which it sounds like you are. No need to change unless you stop progressing.
Same goes for changing programs, sets, reps, rep styles (drop sets, timing rest, etc.). No need to change anything as long as you are progressing.
I don't know your goals, but the only thing I would change is the examples you gave look like you will make a lot of progress with your upper body, but perhaps not so much with your lower body. You could consider squats and deadlifts instead of machine leg stuff. Those heavy type lifts stimulate a lot of muscle growth in your lower body where machine lifts might not be.
But take that with a grain of salt too. If you are happy with your gains, then don't change a thing.
Good luck, sounds like you're getting it done.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
