Hello and welcome to forum!
All rugs appear hand knotted
1st appears to be kashmir silk from India perhaps 1980s,
2nd appears to be southern kurdish / afshar rug maybe antique from 1910,
3rd / next the same carpet,
4th Hamadan Sarouk in finer weave but not quite the expected quality of true Sarouk, around 1950's
5th Good Lilihan 1920/40's,
