the top one is not...it appears to be a cheap, Made in India "wanna be cloisonne" piece made with stone chips.
The little box with the orange flowers appears to be a fairly nice piece of cloisonne, likely stamped "CHINA" on the bottom....not too old but not new, made about 1900.
The little "tea pot" appears to be soap stone....or another stone....carved...with a chop mark on the bottom that is not clear enough to read....again don't know how old, but not new and quite nice.
The last piece looks to be an incense burner....can't tell what it's made ofm nor see the bottom or the inside.
Again not new.

All the above items are from antique shop. The teapot and the incense burner are made of copper. The first 2 are made of some metal or copper material.
