Welcome Ali. The two stamps on the left are early Austria 1883. They look like Scott# 42 3kr green and #43 5kr rose. The other two are Hungary. The first (the one on the left) is either SCott#25 3k rose perf 11.5 or 12 x 11.5 (1888-98) or SC#38 5k rose per 12 x 11.5 (1898-99). This second one would be watermarked #135. The second Hungarian with the denomination in rose is either 1874-76 SC#15 5k rose perf 12.5 to 13.5, or SC#15b perf 11.5 and compound OR 1881 SC# 20 5k rose perf 11.5, 12 x 11.5 watermark 132 OR SC#20a perf 12.5 to 13.5 compound. Simple no? Unfortunately none are in very good condition so value would be minimal.
It looks like these are together on an album page. During this era they were both part of the Austro-Hungarian empire, which might explain why they were catalogued together.
It suddenly occurred to me you may not have access to a Scott's catalogue, so the watermark numbers would mean nothing. Here are images of the two watermarks I mentioned. #132 kr in an oval and #135 Crown in oval or circle, sideways. Hope this helps.
