Is there a profile Manager in portable ? like http://support.mozillamessaging.com/en-US/kb/Using+Multiple+Profiles , I need to delete a couple identities and the manage identities will not allow me to delete any, and all of a sudden it only shows one but on the left pane and in settings there are 3....using different outgoing settings.

As with the other Mozilla apps, the portable version uses a single profile called 'profile' in the Data directory. Identities are all contained in that single profile.
Sometimes, the impossible can become possible, if you're awesome!
Is there a specific file to edit or delete ? I don't see anything that seems like it would contain my names. I do how ever see in J:\PortableApps\ThunderbirdPortable\Data\profile a folder called "mail" and that contains a few local host type folders and a hotmail folder etc, and in each of those are files for drafts, trash, sent that kind of thing but nothing that seems so easy as to the profile name or any file that seems like it would have them in there.
I found the way, in the program via Tools/Account Settings, select the account in the list on the left then at the bottom it has a Account Options drop down list and you can remove from there. I was clicking the Manage Identities on the lower right in the same section. BUT, the above post might still come in handy and I will explain that one in detail tomorrow, it's 3:35 AM here....
Is there a way to create a new profile ? or a 2nd profile ? I want to be able to have it so when TB starts it asks so that either my self or my kids can sign on and not see each others mail.
This solution is not for novices and not for serious security....
Make two installations of ThunderbirdPortable. You'll have to use two separate directories, such as x:/PortableApps/ThunderbirdPortable and x:/PortableApps/DadsThunderbirdPortable. Password protect yours.
If anybody would want to, they could easily use other tools (other than ThunderbirdPortable itself) to read the mails that are in the mail folder, so this is not really a very good security system. Even if you had two separate profiles (like you a trying to do), this would still be the case.
However, the same thing would happen if you used almost any other email client that did not provide absolute encryption or a secure container for your mail. If you are serious about security, you'll have to follow that lead.
Please consider that although you don't THINK the kids could figure out a way around this simple system, if they want to, they will.
So to answer your question about square 1, you aren't really at square 1, you aren't even on the game board yet.

use this. Then you can use several profiles without having 2 or more separate installations using up space.
And you can rename them to "Mark's emails" and "Dad's emails".

It is a good fix/work around and some what useful, it will do what I want Thank you. The bad is as (J Neutron ) stated security, someone could still read someone elses emails simply by clicking any profile, even if it's pass worded, if they are saved locally or simply go to the stored folder and open them easily. So then it's really a trust issue
To bad it can't be similar to an IM or web based email where you sign off or sign on as a different user and can't see the other persons things...But it works, Thanks again Simeon, as usual 
It's been a while since I used a standard install of Thunderbird, but I was under the impression that it keeps separate profiles in the OS User Profiles in the Documents and Settings folders (or Users folders in Win7). So for normal users, you would switch OS users to switch profiles.
However, PortableApps does not support multiple user profiles in its launchers - files normally going to the OS User Profiles are redirected to the Data folder. So, the limitation is not due to Thunderbird, but rather to the PortableApps format.
Am I right?
I made this half-pony, half-monkey monster to please you.
I went to the link provided above by simeon https://portableapps.com/support/thunderbird_portable#second_profile and at the very bottom it says, "Note that only one profile can be used at a time, even with MultipleInstances turned on in the advanced launcher INI. This is a limitation of Thunderbird itself.", it is located on this PA website so maybe they left out it's only a limitation of portableapps and not the local install, I'm not sure....because I am reading/following/ this article for the local install of TB, http://support.mozillamessaging.com/en-US/kb/Using+Multiple+Profiles .
would be the solution, but then you have to use installed version and not the portable one.
Installed version will use the current user of windows to store its bits somewhere.
So here we talk then about different thing. This clearly can not be done with portable version as we can not have writing rights to this and that on a fat32 formated usb stick, for what the portable version was designed after all.
To separate windows profiles, you need ntfs formated space with rights allocation enabled, such device is then no more portable at all, it works on one computer and its windows rights management only.
So if you use proper restricted users accounts under some recent windows version, you can make installation fine.
If you place the portable version somewhere, possible also on a drive with fat32, then all is readable for everybody at any time.
This is BTW common to most mail clients I had look at in recent times. Only outlook for example will provide kind of slightly encrypted containers for all files , or at least among those 6-7 mail clients I have checked recently.
