So I noticed this on my hamster's back it looks like mosquito bite but I'm not sure that's it because he has also started losing his hair..

Thanks for reaching out about Bobo and including photos, although difficult to determine a lesion by the pictures. Do you have mosquito problems? External parasites such as mites or fleas are possible, as are bacterial skin infections. Try cleaning the area with a mild soap. If the lesion or hair loss progresses, a veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Good luck.
