You can use g_object_set_data() and g_object_get_data(). First, set the data:

g_object_set_data(G_OBJECT(my_edit), "my_label", my_label);
g_object_set_data(G_OBJECT(my_edit), "age", GINT_TO_POINTER(age));

and in the callback you can get the data like so:

gint age = GPOINTER_TO_INT(g_object_get_data(G_OBJECT(widget), "age"));
GtkWidget *my_label = g_object_get_data(G_OBJECT(widget), "my_label");
