The first picture says (reading right to left, top to bottom) Da Ming Xuande Nian Zhi, which means it was made during Emperor Xuande's reign. Nian means year and zhi, if I'm not mistaken, means "make".
The second picture starting from the right, top to bottom, means the head (tip) of a pen (or I guess brush in this case) doesn't stop, and the middle line is apparently a phrase referring to scholars who keep writing. Someone else I'm sure can give you a better idea and correct whatever mistakes I've made. My wife thought the whole section might be a stamp placed on it after it was made. The two characters on the right side of the square seal in the second picture means Weiyang, a city or district name. The top character on the left is Wang (King) and my wife couldn't read the last one.
I didn't ask about the third picture. Hope this helps.
I'm just speculating here, but it might be a case intended to hold documents of some kind. Anyone know?
Here is some basic info on the Xuande emperor:
