Problem with my QTRX-HD-31RC Reflectance Sensor Array

Hello ,I lost components that I do not know their nature in my QTRX-HD-31RC Reflectance Sensor Array, I did not find in the datasheet, can anyone tell me the importance of these components and how I can repair my circuit. The components are circled in red in the attached photo


All of the components you circled are decoupling capacitors, so your board might work fine without them. The caps you circled on the left and right are 0.1µF, and the one you circled in the middle is a 1.0µF.
