How to take a photo with a house number with ps?

First put both pictures in ps (there are two layers after putting them in). Then drag the picture of the house number directly to the picture of the gate and put it in a suitable position. After the position adjustment, the color of this picture will be unified. Then you can use ctrl+u to adjust the saturation/hue and adjust the hue of the whole picture. According to this step, it should be ok!
