As part of a package deal, the Sony 75-300 is tough to beat, but as a seperate purchase, the Tamron 70-300 Di LD is a better choice.

Your #2 & #3 are identical. Tamron makes the 55-200 Di II LD, and Sony paid to have Tarmon put Sony's name on them, so Sony sells them as the 55-200 DT. Your #1 is the same lens, but with Sony's own autofocus motor in the lens. Your #1, #2, & #3 are all the same lens.

#4 is also an excellent choice. It's longer that the others and does 1:2 macro which the others don't.

#5 is an older lens, and it's good for the price. If money was a big concern, I might be tempted to get this one. Otherwise, I'd get #4. I'd skip the first three. They don't give you anything that #4 doesn't.

After 200, the Tamron 70-300 Di LD isn't great, but the 200-300 is there if you need it, which can't be said about the 55-200 lenses.

And if it were great, it would cost a lot more, like the Sony 70-300 'G'.

Tamron makes a similar lens to the 70-300 Di LD, but it doesn't have the "Di". It's not as good. If you don't see the "Di", let it pass.

You may notice the gap between what the two lenses can do, depending on what you want to shoot. You need to decide what's more important to you. Is is the 55-70mm range you'll get with one of the 55-200 lenses, or is it the 200-300 and 1:2 macro that you'll get with the Tamron 70-300 Di LD? I can't answer that for you.

One thing that might be worth taking into consideration is that Sony appears to be working on a solution to allow Autofocus with SAM lenses (like the one in your first link above) via an adapter with the new Sony Alpha NEX series cameras (these models use a different lens mount compared to the Alpha dSLR models, and need an adapter to attach A mount lenses).

As it stands right now, Autofocus doesn't work via an adapter with the NEX-3 and NEX-5 using version 1 firmware.

Only Sony knows for sure, but I suspect they'll get that capability via an update at some point (allow Autofocus with SAM or SSM lenses via an adapter). So, if you think you might get a NEX series camera at some point, I'd take that into consideration when narrowing down lens choices.
