Yugoslavia Stamps

Hi everyone. I would like any available information you might have on these Yugoslavia stamps. These were part of a shoebox of stamps I bought for $5.00. I may sell them; although I am leaning towards keeping most of them. I would like to know the year of issue, approximate value, or anything else that you can offer. Thanks everybody! I am so glad I found this sight; I am learning so much about these stamps.

Hi,
First stamp (blue one) is porto stamp from 1951.
2. (red stamp) from 1926
3. this one is from 1952 or 1953 I cant tell from the pic
4. from 1925
5. from 1921

All of these stamps are fragmented from full sets and they are canceled not in mint state. That makes them not very valuable. I cant tell you exact value on US market but in Serbia stamps like this go for 3-5 dinars piece (70 dinars = 1 US dollar).
Although they are nice start for beginners.
