Bikes tend to bring less when sold as a mishmash lot such as this. I envision one kindasorta-complete-ish bike, with a few critical parts missing...once you take stock of everything included and keep one of everything, in the hopes of building one complete machine. I'd have to see what-all is included, in detail, to venture so much as an educated, wild-assed, guess as to what might be a viable offer. Too many unknowns here, including: what's present and in what condition, what's missing, how much (and what pieces) you'll want to retain for spares and what the rest is worth, net, if you were to attempt reselling it to offset some of your acquisition costs.

The toughest parts to replace on an ST90 are:

1 - functional speedometer cable

2 - rear turn signal mounts in good condition, not shredded in a laydown.

I have two of these both purchased non running. Paid $200 for one and $300 for another. Exhaust systems are tough to find that don't have rust holes. The rubber bellows that connect the air cleaner to the carb also difficult to find.

Other other hand, there's quite a lot of overlap with CT90 engine parts and the CT90 is very well supported in the aftermarket.

Yes

A good source to see schematics and part numbers is cmsnl.com

Put the following in a google search “st90 cmsnl” and you’ll get to the page. Then do CT70 cmsnl and you can compare part numbers
