I think the first one with Paisley design is a Hamedan from the village of Alamdar and circa 1940, The pink ground one is a Malayer from West of Iran Circa 1970 and the last one is a Jozan Malayer Circa 1950

Srosen,
Hi, I agree with Sharafi:
- rug#1 is a botef design Hamedan, single wefted, white wefts
- rug#2 is a Malayer-- single wefted, blue wefts, floral design similar to Sarouk florals,suppose to have Turkisk knots. I don't think it is a Borchalou as the Borchalou's usually have pink wefts as well as being single wefted. They usually have a Squarish 8-pointed medallion, with a type of herati design and quarter medallions in the spandrels.
- rug#3 looks like a Josan Malayer with the typical Josan wandering border with the serrated teeth... from the Malayer region,but the Josans are double wefted, usually with blue wefts whereas the Malayer's have single wefts. Sometimes they are called Josan Sarouks because of their similar designs, but they are inherently different from Sarouks because the Josan's is purported to have Turkish knots. I can see 3 knots of the same color, which usually indicate that the rest of the knot node is severely depressed.
