My prediction so far, based on @vinipereira's prediction haha
Archery: We already have a quota on men's side, but I think we won't have any issue to get two teams 6 athletes.
Artistic Swimming: maybe a duet but most likely none. 0
Athletics: Very unpredictable... I will use Vini prediction in this case . But, we have so few possibilities of medalists here. I would quote Alison (400m hurdles), Darlan Romani (Shot put), Letícia Oro Melo (Long Jump), Vivane Lyra and Erica Sena (20km Race Walk/Mixed Relay), Caio Bonfim(20km Race Walk)... There are other names, but not so favorites 32-40 athletes
Badminton: one male and one female. 2 athletes
Basketball: It was so frustating we don't qualify in Men's 5x5. We just needed the victory of Spain against Canada. Now, I think we are not going to take this quota through OQT. But, I believe women are in a better phase and they won't have trouble to get it. 12 athletes
Basketball 3x3: After that good performance from our male team at World Cup, I think we may have a chance! 0-4 athletes
Beach Volleyball: Ana Patrícia and Duda are performing so well, and we don't have problems to qualify full quota. 8 athletes
Boxing: Brazil is doing a good job is this sport and was gifted 3 medals in Tokyo. 5-7 athletes
Breaking: I was expecting better results from our team. The female basically has to win Panamerican Games, otherwise is over already. Male's team has a better chance, but I can't see any of them qualifying yet 0-1 athlete
Canoeing - Slalom: Ana Sátila is qualified. There is an internal issue in our federation, Omira Estácia is Ana's sister. Both got quotas from last Worlds, and there's a chance that Ana will give up of one her quotas, to allow her sister to compete at Olympics. Of course it would be bad for our chances of get a medal, once Ana is some steps ahead of her sister. I don't know what happened to Pepê, I think he didn't compete, but he would be our best name at men's side. At least Ana's sister, now the french-brazilian athlete, had a good performance and should take it on the continental event. 2 athletes
Canoeing - Sprint: the same as usual. Isaquias is already there, but I think it is gonna be harder to take more quotas and events. Even the participation of Isaquias in C2 is at stake. 3-4 athletes
Cycling - BMX: one male and one female in Racing. We already have our female quota. The male is not so guaranteed, but I think we will get it eventually through some event. Brazil is improving in the Freestyle competition, I think we won't get any quota, but it's nice to see that we may participate in OQS and being competing among the tops 2 athletes
Cycling - Mountain Bike: After Avancini retirement, our chances in this sport went down quickly! We wil take probably one quota at each side 2 athletes
Cycling - Road: After an absence in Tokyo, Brazil will return here in both sides. That's already a conquer for us 2
Cycling - Track: We are very far from any chance of qualification, unfortunately we won't take anything 0
Diving: We are improving a lot here. We already have two athletes qualified, and I think we can grab more 4 athletes
Equestrian: Looks we just got our Jumping Team Quota, so now it's Dressage and Eventing moment to take it in Panamerican. I think we will get it. 9 athletes
Fencing: Hardly ever to get a team quota. But, we have good chances to get some individual quotas. 3-4 athletes
Field Hockey: It's unbelievable how we don't evolve on it. We are going to participate at Panamerican Games, but no chances. 0
Football: women's team already qualified, but for men it's always a gamble. And our coach is terrible, so I am really worried if we will qualify. 18-36 athletes
Golf: That's another sport where we have a huge gap to improve. 0
Gymnastics - Artistic: So, it's already confirmed that we won't have men's team. But, women's will be very easy. 8 athletes
Gymnastics - Rhythmic: We already have full quota 6 athletes
Gymnastics - Trampoline: I think this time we will get one female quota. With some luck we can grab even a second female, or male quota. 1-2 athlete
Handball: women's team is likely to qualify, but the men's is never certain. 14-28 athletes
Judo: I think we will miss two or maybe three categories this time 11-12 athletes
Marathon Swimming: Ana Marcela will likely qualify, and I think Jungblut may take it too. For male, I believe we will miss it 1-2 athletes
Modern Pentathlon: probably none? With some luck someone could qualify. 0-1 athlete
Rowing: Verthein should qualify at continental event. 0-1 athlete
Rugby Sevens: Women's team is already in, but for men's team is unlikely 12 athletes
Sailing: Our performance at Worlds could be much better, but I think we will miss just two events. 10-14 athletes
Shooting: We already have one quota. I am otimistic here, I think we can grab more one or two. 2-3 athletes
Skateboarding: not as easy this time to qualify the full quota. We may lost one quota at men's street 11-12 athletes
Sport Climbing: Unfortunately we don't have any chances here 0
Surfing: not likely to qualify 2 female athletes like in Tokyo. But, we still can qualify the third athlete for our male team 3-4 athletes
Swimming: Again, I will use Vini prediction here. I quite pessimistic about this sport. We just have one or two actual chances of medal. 22-28 athletes
Table Tennis: We have full quota 6 athletes
Taekwondo: It's hard to predict, but I agree with Vini's prediction 2-3 athletes
Tennis: MS, MD, WS, WD all seem possible. 5-6 athletes
Triathlon: some good results lately. I think we will take 4 quotas easily, but there is a chance to have 5 athletes 4-5 athletes
Volleyball: what a disaster would be if we don't qualify both teams. 24 athletes
Water Polo: Again, other sport that isn't so well-worked. 0
Weightlifting: I don't know what happened to Natasha who didn't compete in Worlds, maybe she retired, but we have two good athletes that should qualify. 1-2 athletes
Wrestling: Always difficult to know but I think we have a few athletes that could get the quotas. 2-5 athletes
