The company gets to decide what airplanes to offer to the pilots who are being displaced. They bid and get awarded in seniority order, but only among those being displaced that were offered that specific bid. Most likely the FOs who were hired by NJI will be displaced to the right seat in the Globals, even though their company wide seniority wouldn't hold it and the company has said that they will only use company wide seniority order. The company tells a lot of lies and has a history of protecting the NJI pilots (especially with two of the higher management positions filled by former NJI pilots). Everyone already in the Gulfstream has their seat protected as long as the airplane they are on is not displaced. The G-IVs have already started to get sold so unless the pilots on it get a bid into the G-V before the IVs are gone, they will be at the mercy of the company to offer the Globals to those getting displaced- they might get it, they might not.
