Question about chainring wear

I'm swapping some parts onto my bike and upon closer look at the chainring, it looks like some of the teeth are worn down a bit compared to the others. Is this an issue? It looks like I can unbolt the crank arms and replace the chain rings on here if I need to since they aren't riveted.

also, I currently have a 2x7 drivetrain with a 48t large chainring. Can I keep the front chain rings while swapping the 7 for an 8 in the rear? The one pictured below is 52t
