After removing old system app and installing the new version, it forces close
I cannot say for all apps you listed -- but for some, the following applies:

Some system apps (as e.g. the market/playstore app) have to be present in /system in order to work. For the Playstore app, the reason is: The permission to install other "packages" is only granted if one of the following two conditions is met:


it is signed with the same certificate as the system (ROM) itself -- which does NOT apply in your case, due to the custom ROM used
it is installed as "system app" (i.e. below /system) -- which did no longer apply in your case, since you uninstalled the app from there


Expecting the pre-conditions given, developers might have forgotten to include a check and implement appropriate exception handling -- which then may lead to the described force-close.

Similar constellations might apply to other apps/packages as well -- though I'm not sure what should make the Google Translate app so special (maybe it has some special hooks I missed).

You could try to find out by following Roxan's advice, to integrate the app as "system app" again using e.g. Titanium backup, and see if it still force-closes.
