Sorry, I can't be much of help. It is written in classical Chinese and I can't understand it. I know almost all of the characters, but I've never studied classical Chinese to a very high level. Even a Chinese person couldn't tell you the meaning unless they studied classical Chinese to a high level and maybe used reference material probably. I can tell you in the first picture I see the name Qian Long, who was an emperor. This might be mentioning him or that time in history. Here is the Wikipedia article on that emperor if you have any interest.

In the third picture it says Fugaofang Shanjiangcun Liang(ji)tu. This is a description of the picture; it's the pictures name and the town it's from.
I can read a couple characters in the stamps, but that's all. They are usually old Chinese characters and hard to read. One is probably the stamp from the person that painted it. They use blocks to stamp official documents and stuff like a signature.
That's about all I got. Sorry I couldn't help more. I can ask my wife when she gets home, but I doubt she can help much more.
