I would like to number some equations like this

Chapter.eq_no
1.1
1.2a
1.2b
1.2c
1.3

Is that possible?

Yes, see section 19.4 of the math manual that comes with LyX 1.5.4.
(add this command to your document preamble:
 \numberwithin{equation}{chapter}
 and set the mat option "use AMS.." in the document settings )
