First coin I think is Nepal, second is Tibet. Very roughly 19th century, datewise. These can be dated/attributed a lot more precisely, if you have the right catalogues and are willing to squint for a while (or if you are an expert in these series, which unfortunately I am not.)
Pretty sure those are from Tibet. Look up "tangka" on numista Dating them can be a bit tricky. Here's a summary I wrote on IDing Tibetan coins.
