They woke me from my sleep and I am here :-)
many of the texts pointed out by Frank are excellent, at least those I know. I am not sure I understood your goal, Maxiteris, but often beautiful musicological texts do not limit themselves to giving you a list of forms and exercises for practical purposes; nowadays, the focus is on the panorama rather than the single event. For this reason, in Bianconi's volume, for example, there isn't a true list of possible 17th-century dances and forms.
My advice, instead, is to set aside a morning in a library (a musicological library, therefore, inside a conservatory, for example) and work with encyclopedias. Grove and MGG above all; Grove is more convenient because it is in English, MGG is in German... Look for the most generic entries and base yourself on the bibliography that the encyclopedia provides. So, I don't know, you look up "Suite" and go to check the individual entries of the common dances of the Suite. You will at least immediately have a definition and some very well-known examples. The exercise, then, follows naturally: in the same library (or online) you look for the score of an exemplary Giga and try to analyze it, perhaps by playing it or, even better, go home and watch all the interpretations of that Giga you find on YouTube, trying to understand the performance practice (that is, the way musicians expert in that repertoire play those pieces; when talking about Baroque or early music, this is a VERY important thing).
You will realize that it is neither a short nor a simple task...
Potentially every book of musical analysis has a section dedicated to forms. Little-known forms are another matter, and there the encyclopedia is the best (first) approach.
Postscript: a very easy way to understand how many different forms were practiced in the Baroque period (and before and after) is to take a catalog of a prolific author. I don't know, look at the catalog of Telemann's works (https://it.wikipedia.org/wiki/Composizioni_di_Georg_Philipp_Telemann). On Wikipedia it is even incomplete and does not give you the possibility to look at the parts (and therefore their internal subdivision, for example). But this very simple little exercise leads us to discover forms that are never talked about: the canon (which seems easy but is very common in this period), the Rigaudon, the Passepied, Marches and Fanfares, Overtures. All this, I repeat, with books closed, in the sense that each of those Overtures will have movements in different forms; every Partita, every Concerto, every Opera will have very different forms. I won't tell you how much fun it is to look at Mozart's catalog :-)
