I've opened old sfd file which is long text file and the only license information I've found is something like this:

2018 Microsoft Corporation. All rights reserved. Microsoft: Consolas Bold Version 7.00 Consolas is a trademark of the Microsoft group of companies Microsoft Corporation Luc(as) de Groot http://www.microsoft.com/typography/ctfonts http://fontfabrik.com Microsoft supplied font. You may use this font to create, display, and print content as permitted by the license terms or terms of use, of the Microsoft product, service, or content in which this font was included. You may only (i) embed this font in content as permitted by the embedding restrictions included in this font; and (ii) temporarily download this font to a printer or other output device to help print content. Any other use is prohibited. http://www.microsoft.com/typography/fonts/default.aspx

Another file (consolasboldmod8.2.sfd) has this text: "Copyright: (c) 2018 Microsoft Corporation. All rights reserved." which I believe is not open source either.

Some files have empty copyright, some files have string "Copyright: Consolas is rightfully public domain it isn't copyrighted by Microsoft or anything". I believe there should be some additional cleanup work to be done.
