Sorry but neither of these is an aerogramme - they are regular prepaid covers that were quite numerous in the USSR /Soviet Union.
The first one is for inland ground mail (the 4-kopeck postage rate), the other three are for inland airmail (the 6-kopeck postage rate). When used for sending a letter to abroad they needed uprating with additional stamps to 16 kopecks in total for Cairo.
Someone tore the additional stamps off these covers, and they are just a useless trash now
