As Bruce says, "to have respect for someone" is probably the most common phrase, meaning that you hold them in high regard or esteem. You can also use "to show respect towards", which I think has has a very slightly different meaning; more like honoring someone, or demonstrating that you hold then in high regard through your actions.

Hello Gerda: How is right to say "He has no respect to/for anyone/someone? Can I say towards anyone/someone?" The most common usage is to say "He has no respect FOR someone or anyone.". --Warm Regards, Bruce
