a) None of those are stealth.
The F-22 is (in fact it has better stealth than the JSF) and so is the B-2 (also has better stealth than the JSF, but you called it out in your other reply so we'll let that one slide).
The others don't need stealth to fulfill their respective roles.
b) None of those can fulfill the roles of any of the others.
Correct. The F-22 is extremely stealthy and will clear our whatever aircraft the enemy puts in the skies. It also has limited ground strike capability, but that's a real waste. The B-2 (also extremely stealthy, possibly more than the F-22) is then clear to come in and start really pounding ground defenses. You take out all the stationary radar, SAM sites, AAA, C&C, etc with that while the F-22 provides protection. You don't risk lucky shots against your B-2s by sending them after less heavily defended targets; you just use them to clear a path for your remaining forces so they don't face anti-air defenses.
Once all appreciable anti-air has been destroyed and the enemy can't put a plane in the sky without F-22s dropping it, you're free to send in your non-stealth aircraft. F-16s bomb the Hell out of stationary targets and can provide some target-of-opportunity strike capability. A-10s take out mobile infantry, supply convoys, etc. AC-130s and A-10s provide your close-in air support for whatever ground missions you need to complete your objectives. Each has its own distinct role to play; one thing it's great at doing. Used together, you get the best of all worlds.
c) They're all old designs that don't look good on a budget request.
Depends on what you mean by "doesn't look good on a budget request". As a taxpayer, they sure as Hell look good to me. They're much cheaper than JSFs and each is much more capable at the specific job it's intended to do. Those "old designs" have all the bugs worked out of them and are reliable as can be. And when one does break down, it costs peanuts to repair or replace it. If the folks in charge of the budget don't think that looks good, we need to fire them immediately.
d) Particularly a $1 Trillion request.
We could buy so many of those things for $1 Trillion that we wouldn't have pilots to fly them all. So we'd buy a few less than that and train enough pilots to fly them. The result would be a force so large that we could run dozens of simultaneous sorties 24/7/365 and overwhelm anyone anywhere with omnipresent force.
So we'll have a very expensive plane that does nothing particularly well, but we'll have a lot of them, and against almost any opponent we're likely to face it will be literally invincible because getting through stealth (even the Gen 1 Stealth of the F-117) is a lot harder then it looks in a Navy white paper.
Actually, getting through stealth isn't that bad when using low-frequency ground based radar. Getting through it in the air is a challenge. That's why the advanced stealth of the F-22 and the B-2 are a much better fit for early combat: they'll have vastly better survivability than the JSF. For later in the campaign - when the enemy no longer has effective anti-air defenses - there's no reason to fly significant amounts of costly aircraft sorties. At that point, you want to fly legions of cheap, effective aircraft in and pin down the enemy so they can't so much as glance out from under the rocks they're hiding under without JDAMs raining down on them from all directions.
