They are estimating the payment will be around $35 per claimant. The settlement has not yet been approved; this website is performing no small amount of data gathering which the class action lawyers will no doubt use as evidence that the settlement should be approved.
There are a variety of objections. (Imagine if these could prevent the settlement from being approved by the court and the class action counsel wants to make them go away.)
Some of the objections asked not for more money but for the settlement to require Facebook to change its behaviour or to admit guilt. Some argued the settlement was just a way for Facebook to avoid further discovery. Quite a variety of feedback. Angry Facebook users.^1

1. There's also some discussion of another website that takes a 15% cut of the claimant's settlement payment in return for the "service" the operator provides. He is objecting to the settlement because the settlement administrator is rejecting the claims he is submitting on behalf of other claimants. https://claimclam.typeform.com
