Absolutely, raise/call when you hit itThey assume you would slow-play if you actually hit a paired flop.
You're right, paired boards are good to bluff at when checked to because it is less likely that your opponent has hit the flop. You will need to re-evaluate if they call you though as if they flopped trips they are likely to check it to you.
It is better to give more information with your questions like history with opponent, reads on them, stack sizes, what hand you hold, board texture etc. etc. With more info you will get better, more helpful answers.

Today I got A8 board 775, but I was OOP.I still cbet bluff. I am not sure if it is right.It is kind like a WA/WB situation. if the board is 77J will it be better or worse.
Way ahead of what exactly? you have A high, you're not way ahead of anything.
I'm going to generalize here but what the heck.
*Against bad players who aren't huge fish raising most paired boards is often a good bluff.
*Against good players who hand read make sure it's believable. If you flatted from UTG+1 no-one will believe you hold a 2 on that 722 flop. However on a KK2 flop your fully believable.
*Against huge fish (53/22 or so) I wouldn't bother raising with air. They're fish, they're there to be value towned. 722 flops may see AQ/A2/33/A7/JT or any old shite come along.
*Lastly this is best done with a little equity. Pure outs aren't needed but an overcard or two is better than small pps so we do have equity vs pairs.
