To help clarify, the first one is open delta/open delta, and the second one is open wye/open delta.
3 phase open delta voltages - 2 single phase transformers

It's not drawn right.What would be the 3 phase voltage from this configuration?
Would it be 208v or 240v 3phase?
Thanks

Has many errors that I see in my world.
H1 & H2 are labeled incorrectly and don't follow IEEE guidelines.
The primary is drawn like open delta, the secondary is all screwed up.
Three bushings yet two designations. X0 is a common point and is generally found on pad mounts where the coil windings are internal and can't be changed as easily as a single transformer.
Also, the secondary bushing on the right transformer is missing a lead. It needs to be tied to the other transformer secondary lead.
So for that one I see a single phase 240 volts, but there will be no high leg voltage because the coil is floating and doing nothing.
Where is this picture from?
