Lately I have gotten A LOT of punctures and now comparing them I saw they look the same, but I have no idea what these punctures could be. I checked the insides my tyres multiple times but I didn‘t find anythinh abnormal. These are all on the SIDE of the tube, sometimes multiple ones next to each other, but they are not all on the same location on the tube. Does anyone know what could cause that?

Those look like classic pinch flats, caused by your tire pressure being too low. When you hit a bump (e.g., pothole or curb) the underinflated tube pinches between the tire and the rim.
If you don’t have a bike pump with a pressure gauge, I’d recommend having one on hand. If you’re used to kids and mountain bike tires, road bike tires (including slightly larger 700×30-40mm range) need higher pressure than you might be used to; also, tires naturally lose a bit of pressure through osmosis, so check your pressure every week or so.
