It's a non-US e-ticket receipt thus no baggage allowance necessary in the body of the e-ticket receipt. But, if OP looks carefully, there should be links in what ought to be a 3-4 page doc.
This one is a bit of an oddity. Ordinarily, your allowance is the allowance for the marketing carrier of the first segment. Thus, one bag for all segments (I presume that you mean one ticket, not just one PNR).
But, because Brazilian law requires two bags for flights to/from Brazil, you will have a two-bag allowance on those two segments.
Your allowance will thus be:
CDG-JFK 1 bag
JFK-GIG 2 bags
GIG-JFK 2 bags
JFK-CDG 1 bag *
* - Presumes that you are also stopping over rather than connecting on the return. If connecting, your 2 bags will be checked through to CDG.
