To me, the double arrow on the middle one means “first page” and “last page”, not “previous page” and “next page”. The other two are fine.
That part worries me a bit, though. I’ve lost count of how many otherwise-good sites I’ve come across which have reduced their page menu to a size which is almost impossible to use. Please ensure that there is a large enough target area to click, and clear “dead” space between numbers, to reduce the possibility of clicking the wrong one in error.
If you don’t understand why - or think it’s an issue which will only affect a tiny percentage - then I suggest you watch somebody with a common condition like arthritis try to make fine movements with a mouse. It’s very enlightening.
