The name line is reserved as some character names are long - one of the longest just barely fits on the line. I think there's been a revision since this to move them to the left to stop them from being crowded on the right hand side, if I recall correctly, but I can't move them too much further because there's a couple character portraits that take up more horizontal space.
Additionally, status ailments clear at the end of battle in the current build - in return, they're slightly more dangerous in actual combat to encourage you to cleanse them as opposed to letting them linger until the battle resolution takes care of them. Poison, left unchecked on top of incoming damage, can incapacitate a character in a few rounds.
Experience is spaced to take much larger numbers - with all numbers in place, the EXP text rests 32 pixels to the left of the first number. HP could, potentially, collapse in a little bit - it only needs to fit an additional two characters onto the line to accommodate the largest health possible. My only worry is that putting MP on that line as well will be too crowded when health tips above 1000 and with MP in triple digits - I might mock it up with it there and see how it looks.
My thoughts are to find a way to potential delay it in the empty space below the portrait, between the level counter and the HP/EXP display.
