I can not choose many edge.
You need to use the 'sub-element' selection option.
In the selection arrow tool you can change it to this (white arrow) or you can hold CTRL+SHIFT to temporarily switch to sub-element selection.
Then select just the edges you want and chamfer them - but choose the option to 'apply to all' otherwise only the last edge you selected will be changed.
You must do them all at once otherwise if one edge is chamfered, it will not be possible to chamfer another adjoining edge.
You will have to edit out the existing chamfers, select all the required edges again and apply the chamfer to all of those edges at once.
